Changes: 2006-07-10 valentine removed choice. Replaced with Types defined TimePeriodType TimeIntervalType TimeSingleType added GeogLocationType to hold the geometry redefined LatLongPoint as a type defined LatLongBox to hold defined simpleTypes Latitude and Longitude added DataSetLocation Element (type GeogLocationType) to dataset info removed xlink namespace. Just used the xlink concept (problems getting it to compile with xlink schema) 2006-08-30 valentine MANY CHANGES to: sync with the Observations Database terminolog simplify. Removed many unneeded types. (initial version was Type happy) types mostly used only when needed (Geometry, SourceInfo, TimeSeries, Notes, Enumerations). *** Element Case Standardize **** All types are PascalCase All CUAHSI elements and attributes are camelCase * All root response elements are now elements, and not types ** SitesResponse ** TimeSeriesResponse (not timeSeriesType) ** VariablesResponse * extension elements added. ** These are extension points for groups like the USGS that wish to include more information than the normal community uses. * enumerations added * unitType * censorCode (characters used because symbols make for unmaintainable source code) * lt - less than * gt - greater than * nc - no code * variable types consolidated * units element added * consistent siteID/variableID pattern (both include a XXXCode) * Remove many types ** too many to list. * values == TsValuesType renamed from TsValuesSingleVariableType ** split values element out to type ValueSingleVar (c# change tsValuesTypeValueType to ValueSingleVar). ** qualifier elements can be added after the final value element in the Values element. *** we don't know the full list of included qualifiers until we get done with the values. *** at present, qualifiers attribute in the value element is an aggregated field. element block looks like: = values == value qualifers=&quot;A&quot; == value qualifers=&quot;Ae&quot; == qualifier qualifierCode=&quot;A&quot; &quot;Approved&quot; == qualifier qualifierCode=&quot;e&quot; &quot;Estimated. This value has been estimated.&quot; 2006-09-08 variableID renamed variableCode siteID renamed siteCode siteID and variableID attributes added, xxCode removed siteCode name moved into siteInfo 2006-09-15 variable/name to variable/variableName variablePeriod to variablePeriodOfObservation 2006-09-17 added QualityControlLevelEnum added attribute qualityControlLevel to valueAttribute group. (affects ValueSingleVariable) added qualityControlLevel element, and element to the TSValuesSingleVariableType namespace changed to http://www.cuahsi.org/waterML/1.0/ return to types for top level elements, without this they get named getValuesResponse added note to siteInfoElement. We need to put the URL or Retireved from DB not in this block. added TimePeriodRealTime. Need to represent real time data. 2006-0920 variablePeriodofRecorr to seriesCatalog variablePeriodOfObservation to series variableObservationCount to valueCount (to match the OD) added enumerations from the OD valueTypeEnum generalCategoryEnum sampleMediumEnum dataTypeEnum 2006-09-24 queryInfo/criteria/timeParam is now a sequence, since a start or end time can be null The community wants it to be easy, and VB and other .net have problems with some values: converted xsd:decimal to xsd:double. decimal is not well handled by VB converted tsValuesSingleVaribaleType/count from xsd:nonNegativeInteger to xsd:int. 2006-09-28 API signature has been changed to strings. queryInfo/timeInterval/... changed to strings 2007-07-09 ODM seriesCatalog table added columns. Columns now added DataValue element was missing: DataType(eg statistic), Method, Source, and QualityControlLevel. 2007-08-28 added to values method[](methodType), source[](SourceType) added &quot;Unknown&quot; to many enumerations. contactInformation in sourceType changed to unbounded 2007-08-29 DT/DM believes that including an offsetDescription on every element is verbose offsetTypeID attribute added to offsetAttr offsetType Type added, Designed to be a bit more extensible, and handle 2007-08-30 restored attributes that had the offset information on the values offsetAttr restored attr offsetUnitsAbbreviation offsetUnitsCode offsetDescription 2007-11-14 Many services use agency (aka EPA, and USGS) added attributes agencyCode and AgencyName to siteCode. 2007-11-29 SiteInfo/TimezoneInfo min occurs 0 max 1 Series/QualityControlLevel min occurs 0 max 1 2009-07 added back attributeGroup vocabulary attributes got dropp drop VariableInfoType. changes to min/max occurs in several locations A sampling station is any place where data are collected. SiteInfoType is the Element that for the core information about a point sampling location. The core information includes SiteName, SiteCode(s), location, elevation, timeZone information and note(s). SiteInfoType is <siteInfo> in a <site> of a <sitesResponse>. It is derived from SourceType so that other geographic location descriptions can be utilized in the <sourceInfo> of the <timeSeriesResponse> Full name of the sampling site. eg “LOGAN RIVER ABOVE STATE DAM, NEAR LOGAN,UT” A siteCode is an identifier that this site is referred to as. This Code used by organization that collects the data to identify the site. A siteCode has a reference to it's source or network as the @network. For waterWebServices, a site/location is the network plus the value of the sitecode, eg '@network:siteCode' siteCode identifiers often change, so multiple siteCode elements are allowed There may be multiple siteCode elements. Only one should be labeled as the default using @defaultID (set attribute defaultID=true) Multiple siteCode elements can utilize different observation networks may refer to the same site with different identifiers. True if this is the main identifier that this service uses to access this site. default value is false. The abbreviation for the datasource or observation network that this site code is associated with. A siteCode has a reference to it's source or network as the @network. For waterWebServices, a site/location is the network plus the value of the sitecode, eg '@network:siteCode' An internal numeric identifier of the site. Code used to differentiate sites in a datasource. Agency codes are specific to a data source, and are not required nor do they need to be understood by a web service client. optional name to provide more detail about an agency code Specifies the time zone information about a site. The default time zone for this site (+00:00) and if this site shifts to daylight savings time (attribute: usesDaylightSavingsTime) The geoLocation speficies the details of the geographic location. It contains two portions, a geographic locaiton &amp;lt;geogLocation&amp;gt;, and a local location &amp;lt;localSiteXY&amp;gt;. In order to be discovered spatially, geogLocation is required. The geogLocation can be of GeogLocationType, which at present is either a latLonPoint or a latLongBox. There may be multiple localSiteXY, which might be used by data sources to provide other coordinated system information, like UTM and State Plane coordinates. Geographic location: A geographic location is required as part of the site information (siteInfoType or siteInfo element) At present this can be elements of GeogLocationType: LatLonPointType and LatLonBoxType. an xml schema type attribute can be used to determine which type is contained in this element (xsi:type="LatLonPointType" or xsi:type="LatLonBoxType") Site information can contain one or more other locations using the localSiteXY element. The projection string should be stored in projectionInformation. Lat or Northing = Y Lon or Easting = X Additional information should be encoded in zero or more note elmements. The name of the property should be @title, and the value should be inside the note value. Attribute @type is provided so that notes can be grouped. Spatial Reference System of the local coordinates. This should use the PROJ4 projection string standard Elevation in meters. A vertical datum should also be provided. Additional information, like state, county, or other properties like HUC codes should be encoded in zero or more &lt;note&gt; elmements. The name of the property should be @title, and the value should be inside the <note>value</note>. Attribute @type is provided so that notes can be grouped. In order to simplify comprehension, data sources are encouraged to put additional informaiton in the extension area, using thier own namespace. Clients need not understand information in <extension? Alternate name TsValuesSingleVariableTypea aggregates the list of values and associated metadata. It is the values element in the timeSereisResponse Attributes are optional, but use @count is encouraged. The atrributes @unitsAreConverted, @untsCode,@unitsAbbreviation, and @unitsType were originally included to allow for translation from orignal variable units. Thier use is not encouraged. Get unit information from the Variable element. Multiple <value>s represent the data series. multiple <qualifier>s containg the data qualifying comments that accompany the data. <qualityControlLevel> contains the quality control levels that are used for versioning data within the data values Multiple &amp;amp;lt;method&amp;amp;gt;s lists the methods used to collect the data and any additional information about the method. @methodID is the link between the values, and method. Different instruments should be represented as different methods, according to ODM best practices The Sources the original sources of the data, providing information sufficient to retrieve the data value. @sourceID is the link bewteen source the values. <offset> is of type OffsetType. offset lists full descriptive information for each of the measurement offsets. @offsetID is the link between offset, and values. If a webservice has transformed the time zone from the original data. the measurment units of the value elements in this values element True if a webservice has transformed the data from the original units. VariableInfoType is a complex type containting full descriptive information about a variable, as described by the ODM. This includes one or more variable codes, the short variable name, a detailed variable description, and suggest It also extends the ODM model, in several methods: - options contain extended reuqest information. - note(s) are for generic extenstion. - extension is an element where additional namespace information should be placed. - related allows for parent and child relationships between variables to be communicated. One of more elements representing the Text code used by the organization that collects the data to identify the variable. A brief name of the variable that could be shown in a menu A detailed description of the variable. May include processing information and other details. Text value indicating what type of data value is being recorded. For 1.0 this must be from the valueTypeEnum type. A default value of “Unknown” can be used where the value type is unknown. Text value that identifies the data values as one of several types from the dataTypeEnum A default value of “Unknown” can be used where the data type is unknown. General category of the data values from the generalCategoryEnum. A default value of “Unknown” can be used where the general category is unknown. Only terms from the SampleMediumEnume can be used to populate the sampleMedium element. A default value of “Unknown” is used where the sample medium is unknown. The units of the measurements asociated withthe variable. This will be changed to UnitsType in WaterML 1.1 A list of options. Option elements are key-value pair elements that control how a variable maght be utilized in a service. Examples: MODIS web service. Information is aggreated over land or ocean or both. The plotarea option can include: plotarea=land, plotarea=land, plotarea=landocean USGS uses a statistic code, 0003, to repesent a value type of 'Average'. The USGS statistic codes also several options that do not fit the ODM data model. Additional information, properties like should be encoded in zero or more &amp;lt;note&amp;gt; elmements. The name of the property should be @title, and the value should be inside the &lt;note&gt;value&lt;/note&gt;. Attribute @type is provided so that notes can be grouped. This can be used to build up relationships between variables. variableCode for the parent Child or other relationships can be encoded using the related element. In order to simplify comprehension, data sources are encouraged to put additional informaiton in the extension area, using thier own namespace. Clients need not understand information in &lt;extension? Numeric value used to encode no data values for this variable. Element containing the time support (or temporal footprint) of the data values. @isRegular indicates if the spacing is regular. In waterML 1.0, there is a divergence of mean between ODM, and WaterML. WaterML only communcates the regularity, and the spacing of the observations (timeInterval). Whereas timesupport in the ODM is associated with the dataType, and time support. This will be addressed in 1.1 0 is used to indicate data values that are instantaneous. Other values indicate the time over which the data values are implicitly or explicitly averaged or aggregated. The default for the TimeSupport field is 0. This corresponds to instantaneous values. If the TimeSupport field is set to a value other than 0, an appropriate TimeUnitsID must be specified. The TimeUnitsID field can only reference valid UnitsID values from the Units controlled vocabulary table. If the TimeSupport field is set to 0, any time units can be used (i.e., seconds, minutes, hours, etc.), however a default value of 103 has been used, which corresponds with hours This contains information about the request, and is used to enable the XML responses (timeSeriesResponse, variablesResponse,siteResponse) to be stored on disk. When was this response originally created. The URL of the web page that was used as the original source for the response. Often requests scrap HTML pages. This should be the URL of that page. If the response is retreive from a rest URL. This is also a the location for the URL. For debugging, the SQL used to generate this request may be placed in this element. The criteria are the actual parameters that are passed into the method. If you are generate this without a XML helper class, be sure to properly encode these elements. the location or site parameter passed into the site the variable paramter passed into the service the begin and end time of the GetValues request used to generate a timeSeriesResponse. The string submited as startDate to the GetValues method The string submited a startDate to the GetValues method Additional information, properties like should be encoded in zero or more &amp;lt;note&amp;gt; elmements. The name of the property should be @title, and the value should be inside the &lt;note&gt;value&lt;/note&gt;. Attribute @type is provided so that notes can be grouped. In order to simplify comprehension, data sources are encouraged to put additional informaiton in the extension area, using thier own namespace. Clients need not understand information in &lt;extension? variables is a list of variable elements (VariableInfoType). zero or more variable elements are contained in a variables element. See VariableInfoType for more details on the information in the variable element Tthe attribute group vocabularyAttributes contains common attributes used to differentiate data source codes. A network should be provided with a siteCode, and a vocabular should be provided with a variableCode. If there is more than one code, one code should be provided as the default code for the service. @netowrk codespace for the siteCode datasource. Submitted to webservice as 'network:sitecode' @vocabulary codespace for the variableCode for a datasource. Submitted to webservice as 'vocabulary:vocabularyCode' this attribute group provides provenance information for when an object is retrieved from a database. object identifier, or guid for an object time object was created in the database. The default time zone for this site (+00:00) and if this site shifts to daylight savings time (attribute: usesDaylightSavingsTime) The default time zone for a site, specified in hours and minutes: "hh:mm" The daylight savings time zone for a site, specified in hours and minutes: "hh:mm" If the location shifts it's data sources to Daylight Savings Time, this flag should be true. valueAttr contains the possible attributes that can be associated with a data value element. @qualifier contains a qualifier code whose details are described in the values/ qualifier element(s) Space delimit multiple qualifier codes. indication of whether the data value is censored @censorCode codelist is censorCodeEnum. XML date and time at which the data value was observed. This is an ISO specified string, that can contain a time zone offset, if apprpriate. If no time offset is specificed, the data is in the local time zone of the station. text string giving the level of quality control that the value has been subjected to. Codelist is from qualityControlLevelEnum. @qualifier contains a identifier whose details are described in the values/method element(s) @methodID contains an identifier whose details are described in the values/method element(s) Numeric value that describes the measurement accuracy of the data value. If not given, it is interpreted as unknown. If a value is categorical, then @codedVocabulary is set to true, and the categorical term is placed in@codedVocabularyTerm, and a numeric value put in the value. While not a good practice, allows for categorical and numeric values to be intermixed. @sampleId contains a n identifier whose details are described in the values/samples element(s) This is required only if the data value resulted from a physical sample processed in a lab. the standard abbreviation for this time zone (GMT; EST) Hours and minutes offset for this time zone (+00:00). A list of options. Option elements are key-value pair elements that control how a variable maght be utilized in a service. Examples: MODIS web service.

The USGS statistic codes also several options that do not fit the ODM data model. SourceInfoType is used to describe the data source in the timeSeriesResponse. SourceInfoType is the base type for data source information. At present, two types are derived from SourceInfoType: SiteInfoType, and DataSetInfoType. SiteInfoType describes tlocation for a timeseries where that time series is located at a site or a DataSetInfoType describes time series derived from a dataset, such as a netCDF file, or a gridded model. DataSetInfoType describes time series derived from a dataset, such as a netCDF file, or a gridded model. The indentifier which the original source uses to identify this dataset. This may be a unique indentifier, or a URL from which the data source was retireved the default time zone for this site (+00:00) and if this site shifts to daylight savings time (attribute: usesDaylightSavingsTime) Text description describing the data source. Additional information, about a dataset, or other properties should be encoded in zero or more &amp;lt;note&amp;gt; elmements. The name of the property should be @title, and the value should be inside the &lt;note&gt;value&lt;/note&gt;. Attribute @type is provided so that notes can be grouped. geolocation describing the spatial coverage of a gridded dataset. In order to simplify comprehension, data sources are encouraged to put additional informaiton in the extension area, using thier own namespace. Clients need not understand information in extension element dataSetInfo element describes time series derived from a dataset, such as a netCDF file, or a gridded model. time series (site-variable-observation) can have three types of time periods: 1) definite start and end time, or TimeIntervalType, 2) single observation, or TimeSingleType 3) Real Time station with moving window of data available, or TimeRealTimeType In order to simplify client development, all types now include beginDateTime, and endDateTime. A fourth type should be added: 4) continuing site, where start is known, and site is still collecting data. This could be a realTimeType, or rename the real time type to TimeDefinedPeriodType. For where a series has multiple observations, and a define beingDateTime as dateTime of the first data value in the series, and endDateTime dateTime of the last data value in the series. dateTime of the first data value in the series. The dateTime is specified in the following form "YYYY-MM-DDThh:mm:ss" where: * YYYY indicates the year * MM indicates the month * DD indicates the day * T indicates the start of the required time section * hh indicates the hour * mm indicates the minute * ss indicates the second Note: All components are required! Date of the last data value in the series. The dateTime is specified in the following form "YYYY-MM-DDThh:mm:ss" where: * YYYY indicates the year * MM indicates the month * DD indicates the day * T indicates the start of the required time section * hh indicates the hour * mm indicates the minute * ss indicates the second Note: All components are required! For where a series is a single observation. timeSingle, beginDateTime, and endDateTime will have the same value. The beginDateTime and endDateTime are provided to simplify usage by clients.They should be be calculated based on the duration stored in realTimeDataPeriod dateTime of the first data value in the series. The dateTime is specified in the following form "YYYY-MM-DDThh:mm:ss" where: * YYYY indicates the year * MM indicates the month * DD indicates the day * T indicates the start of the required time section * hh indicates the hour * mm indicates the minute * ss indicates the second Note: All components are required! Date of the last data value in the series. The dateTime is specified in the following form "YYYY-MM-DDThh:mm:ss" where: * YYYY indicates the year * MM indicates the month * DD indicates the day * T indicates the start of the required time section * hh indicates the hour * mm indicates the minute * ss indicates the second Note: All components are required! Use where a site has an evolving period where data is available. The US Geological Survey real time data is available for 30 days, the realTimeDataPeriod element is an XML duration and woudl be "30d" The beginDateTime and endDateTime are provided to simplify usage by clients.They should be be calculated based on the duration stored in realTimeDataPeriod Duration Data Type The duration data type is used to specify a time interval. The time interval is specified in the following form "PnYnMnDTnHnMnS" where: * P indicates the period (required) * nY indicates the number of years * nM indicates the number of months * nD indicates the number of days * T indicates the start of a time section (required if you are going to specify hours, minutes, or seconds) * nH indicates the number of hours * nM indicates the number of minutes * nS indicates the number of seconds dateTime of the first data value in the series. This should be be calculated based on the duration stored in realTimeDataPeriod The dateTime is specified in the following form "YYYY-MM-DDThh:mm:ss" where: * YYYY indicates the year * MM indicates the month * DD indicates the day * T indicates the start of the required time section * hh indicates the hour * mm indicates the minute * ss indicates the second Note: All components are required!

GeogLocationType is the base class for the two geometry types: LatLonPointType, and LatLonBoxType. Any additional types should derive from this type. The default spatial reference system is @srs is EPSG:4326 or Geographic lat long. The latitude of the site in a decimal degrees as calculated in terms of the given datum. The longitude of the site in a decimal degrees as calculated in terms of the given datum. Point type for describing a geographic location South Latitude West Longitude North Latitude East longitude. Box type describing a geographic location. The longitude of the site in a decimal degrees as calculated in terms of the given datum. The latitude of the site in a decimal degrees as calculated in terms of the given datum. Series catalog represents a list of series, where each separate data series are for the purposes of identifying or displaying what data are available at each site. Additional information, properties like should be encoded in zero or more In seriesCatalog note elements are placed at the top, to simplify human identification, since there can be tens, or hundred of series for a location. The name of the property should be @title, and the value should be inside the note element. Attribute @type is provided so that notes can be grouped. Separate data series are for the purposes of identifying or displaying what data are available at each site. Site information is a parent of the series so that it does not need to be repeated (difference from the ODM. ). A Site contains one or more seriesCatalogs which contain one or more series. Assotiated with site, a series is a unique combination of the textual repesentation of ODM series: Variable,Method,Source,QualityControlLevel. An ODM series is a unique site/variable combinations are defined by unique combinations of SiteID, VariableID, MethodID, SourceID, and QualityControlLevelID. Text value that identifies the data as one of several types as found ing dataTypeEnum this describes the time period that ana variable or observed parameter are available for. This is of TimePeriodType, which is presently: TimeIntervalType - definite begin and end TimeSingleType - single observation/datavalue TimePeriodRealTime - a floating time period for when data is available. This will have a xml schema type attribute: xsi:type="TimeIntervalType" xsi:type="TimeSingleType" xsi:type="TimePeriodRealTime" Text value indicating what type of data value is being recorded as listed in valueTypeEnum General category of the variable as listed in generalCategoryEnum The medium of the sample as listed in SampleTypeEnum Method description. Optional, since many sources do not have detailed methods. ODM datasources require methods. Source of the data values and reference information to recover/discover the data from the source.

This field can be populated with “Unknown” if there is no title for the data. Abstract of data from a specific data source. Abstract field should be populated with a more complete text description of the data that the metadata record references. This field can be populated with “Unknown” if there is no abstract for the data. Name of metadata profile used by the data source Link to additional metadata reference material. OffsetType contains full descriptive information for each of the measurement offsets. A set of observations may be done at an offset for the central location. offsetTypeID links to dataValue/@offsetTypeId offsetValue element is value of offset. If 0, then offset is not needed, and offsetTypeId should not be included on the dataValue Full text description of the offset type. Field should be filled in with a complete text description of the offset that provides enough information to interpret the type of offset being used. For example, “Distance from stream bank” is ambiguous because it is not known which bank is being referred to. Units of the offsetValue By default, the offset is vertical. If the offset is horizontal, then this becomes a direction, and distance from the observation point if offsetIsVertical=false, then this is the direction of the offset Unique integer identifier that identifies the type of measurement offset. Suggested that this is offsetType from ODM database.
