WITSML - Common Data Component Schema An identifier to indicate the data originator. This identifies the server that originally created the object and thus most of the uids in the object (but not necessarily the uids of the parents). This is typically a url. When the data was created at the persistent data store. Last change of any element of the data at the persistent data store. The change time is not updated for a growing object while it is growing. The item state for the data object. Comments and remarks. WITSML - Custom or User Defined Element and Attributes Component Schema. Specify custom element, attributes, and types in the custom data area. Any element or attribute in any namespace. It is strongly recommended that all custom data definitions be added to a unique namespace. A schema to capture a set of data that is relevant for many exchange documents. It includes information about the file that was created, and high-level information about the data that is being exchanged within the file. An identifier for the document. This is intended to be unique within the context of the NamingSystem. constraints:@minOccurs="1" Zero or more alternate names for the document. These names do not need to be unique within the naming system. The date of the creation of the document. This is not the same as the date that the file was created. For this date, the document is considered to be the set of information associated with this document information. For example, the document may be a seismic binset. This represents the date that the binset was created. The FileCreation information would capture the date that the XML file was created to send or exchange the binset. A document class. Examples of classes would be a metadata classification or a set of keywords. The information about the creation of the exchange file. This is not about the creation of the data within the file, but the creation of the file itself. Information about the security to be applied to this file. More than one classification can be given. A free-form string that allows a disclaimer to accompany the information. A collection of events that can document the history of the data. The owner of the data. WITSML query parameters. An optional comment about the document. A structure for WITSML query parameters. The intent is to allow a query for all objects within an index range (whether or not the object is growing). These would typically be something like a daily report. The minimum start time for an object. This only applies to objects with a root level date and/or dateTime element(s). The objects may or not be growing objects but the See the API specification for behavior related to this query parameter. The maximum start time for an object. This only applies to objects with a root level date and/or dateTime element(s). See the API specification for behavior related to this query parameter. A block of information about the creation of the XML file. This is different than the creation of the data that is included within the file. The date and time that the file was created. constraints:@minOccurs="1" If appropriate, the software that created the file. This is a free form string, and may include whatever information is deemed relevant. The person or business associate that created the file. Any comment that would be useful to further explain the creation of this instance document. Information about the security classification of the document. This is intended as a documentation of the security so that the file will not inadvertently be sent to someone who is not allowed access to the data. This block also carries a date that the security classification expires. For example, a well log is confidential for a period of time, and then becomes open. All security classes are characterized by their classification systems. The security class in which this document is classified. Examples would be confidential, partner confidential, tight. The meaning of the class is determined by the System in which it is defined. The security classification system. This gives context to the meaning of the Class value. The date on which this security class is no longer applicable. A general comment to further define the security class. The audit records what happened to the data, to produce the data that is in this file. It consists of one or more events. constraints:@minOccurs="1" An event type captures the basic information about an event that has affected the data. The date on which the event took place. constraints:@minOccurs="1" The party responsible for the event. A free form comment that can further define the event that occurred.

The value is only required to be unique within the context of the nearest recurring parent element. This type disallows an "empty" boolean value. This type should not be used directly except to derive another type. All boolean types should be derived from this type rather than using xsd:boolen. This type disallows an "empty" dateTime value. This type should not be used directly except to derive another type. All dateTime types should be derived from this type rather than using xsd:dateTime. This type disallows an "empty" double value. This type should not be used directly except to derive another type. This type disallows an "empty" short value. This type should not be used directly except to derive another type. The intended abstract supertype of all strings. This abstract type allows the control over whitespace for all strings to be defined at a high level. This type should not be used directly except to derive another type. Replace tab, line feed and carriage return with a space, collapse contiguous sequences of spaces to a single space and then remove leading and trailing spaces. The empty string is not allowed. This constraint conbined with the whiteSpace collapse constraint means that a blank value is not allowed. constraints:@minLength="1", This defines the maximum acceptable length of a string that can be stored in a data base. This value should be the smallest "maximum size of a variable length character type" in commonly used DBMSs. This is the maximum size of a VARCHAR2 in Oracle 8.

The intended abstract supertype of all user assigned human recognizable contextual name types. There should be no assumption that (interoperable) semantic information will be extracted from the name by a third party. This type of value is generally not guaranteed to be unique and is not a candidate to be replaced by an enumeration. The intended abstract supertype of all locally unique identifiers. The value is not intended to convey any semantic content (e.g., it may be computer generated). The value is only required to be unique within a context in a document (e.g., defined via key and keyref). There is no guarantee that the same data in multiple documents will utilize the same uid value unless enforced by the source of the document (e.g., a document server). Spaces are not allowed. The intended abstract supertype of all comments or remarks intended for human consumption. There should be no assumption that semantics can be extracted from the field by a computer. Neither should there be an assumption that any two humans will interpret the information in the same way (i.e., it may not be interoperable). The intended abstract supertype of all enumerated "types". This abstract type allows the maximum length of a type enumeration to be centrally defined. This type should not be used directly except to derive another type. It should also be used for uncontrolled strings which are candidates to become enumerations at a future date. The intended abstract supertype of all "units of measure". This abstract type allows the maximum length of a UOM enumeration to be centrally defined. This type is abstract in the sense that it should not be used directly except to derive another type. The meaning of the endpoint for min/max query parameters on "growing objects". The list of standard values is contained in the PRODML enumValues.xml file. The endpoint of the range is inclusive of the specified range value. hat is, a node index value which matches the specified range value is considered to be within the range. The endpoint of the range is exclusive of the specified range value. That is, a node index value which matches the specified range value is considered to be outside the range. The endpoint of the range may be extended to the first encountered value if an exact value match is not found. That is, if a node index value does not match the specified range value then the next smaller value (on minimum end) or larger value (on maximum end) in the index series should be used as the endpoint. Basically, this concept is designed to support interpolation across an undefined point. The endpoint of the range may be extended to the first encountered value if the interval is overlapped with the index interval. That is, if a node index value does not match the specified range value then the next smaller value (on minimum end) or larger value (on maximum end) in the index series should be used as the endpoint. This concept is designed to select ALL nodes whose index interval overlap with the query range. The value is not known. This value should not be used in normal situations. All reasonable attempts should be made to determine the appropriate value. Use of this value may result in rejection in some situations. These values represent the state of a WITSML object. Actual data measured or entered at the well site. Model data used for "what if" calculations. A planned object. That is, one which is expected to be executed in the future. The value is not known. This value should not be used in normal situations. All reasonable attempts should be made to determine the appropriate value. Use of this value may result in rejection in some situations. ================================================================================================= THESE NEED TO BE RECONCILED WITH THE ReportingProduct LIST. ================================================================================================= A timestamp value used for min/max query parameters related to "growing objects". The meaning of the endpoint of an interval can be modified by the endpoint attribute. The element value for which a match is requested. The default is "inclusive". Values of "true" (or "1") and "false" (or "0"). A date with the time of day and an optional time zone. While the time zone is optional, it is strongly advised that the zone always be specified in each date time value. A unitless quantity. This should not be confused with a dimensionless measure. A user assigned human recognizable contextual name of something. There should be no assumption that (interoperable) semantic information will be extracted from the name by a third party. This type of value is generally not guaranteed to be unique and is not a candidate to be replaced by an enumeration. A comment or remark intended for human consumption. There should be no assumption that semantics can be extracted from this field by a computer. Neither should there be an assumption that any two humans will interpret the information in the same way (i.e., it may not be interoperable). A textual description of something. A community assigned human recognizable name. This type of value is intended to be unique and is generally a candidate to be constrained to an enumerated list. A locally unique identifier. The value is not intended to convey any semantic content (e.g., it may be computer generated).

There is no guarantee that the same data in multiple documents will utilize the same uid value unless enforced by the source of the document (e.g., a document server). A reference to the unique identifier of another element. This value represents a foreign key from one element to another. The value should match the value of an attribute of type uidString.
