= Change Request Information =
This page contains information about basic information about requirements to a Change Request (CR). Change Requests can be submitted as an owl file or according to a predefined excel spreadsheet. The data model that is the basis for the entity types and relationships that are used in the spreadsheets is available here:
[http://rds.posccaesar.org/2008/02/OWL/ISO-15926-2_2003]

It contains all the entity types defined in ISO !15926-2:2003 represented as ''!owl:classes''. The file is generated by translating the EXPRESS file lifecycle_integration_schema.exp which ISO 15926-2 (2003) annex B references, to an XML serialization of OWL.

Below is some information related to description of new class content:

||'''Type of information'''||'''Description'''||'''Related predicate'''|| 
||PCA ID||For new items this should be identical to the R-UUID in the defaultRdsId field.||||
||defaultRdsId||Unique ID of the class according to the JORD ID spec. Can be filled out by Proposer or PCA.||||
||RDL Designation||The name of the object (class, relationship or individual). All new classes need a unique name. It is mandatory to provide a unique name for all RD objects submitted.||||
||Fragment||The fragment corresponds to the designation in Camel Case and must also be unique. Exceptions – abbreviations in designation in capital letters and special characters. This column is optional and will created by the system if not provided.[[BR]][[BR]]E.g. a class with designation DESIGNATION IN CAMEL CASE would be designationInCamelCase in this field. The address for this resource would after processing become:[[BR]][[BR]]!http://posccaesar.org/rdl/designationInCamelCase [[BR]] Standard URI encoding should be used for special characters (e.g. -, /,%,#,<,>, all parantheses). Examples:[[BR]] Word word -> !WordWord[[BR]] word word ->	!WordWord[[BR]] word a word -> WordAWord[[BR]] word ISO word	-> WordISOWord [[BR]] word a b c word -> WordABCWord [[BR]]  iTunes ->	Itunes [[BR]] A4 A3 ->	A4A3 4/3 -> 41%2F4||||
||Entity Type||Every class needs to have a entity type according to the data model. The column is defined by the ISO 15926-2 entity type from which the current RD object is instantiated. The file http://rds.posccaesar.org/2008/02/OWL/ISO-15926-2_2003 contains all the entity types defined in ISO !15926-2:2003 represented as !owl:classes.||||
||Creator||The (editor) user who created the Reference Data object. Leave blank when importing new data, leave unchanged when updating or deleting data. Only for internal use.||||
||Creation Date||The date and time that the Reference data object was first imported (or manually created). For internal use.||||
||Registration Status||||||
||Alternative Designation||A new item can have one or several alternative designations. The alternative designation must also be unique.||||
||RDL Definition||Definition of the class. Should be in the following form:       This field is mandatory for new classes. The definition should follow the following structure: A X with/that is/which has ……..[[BR]][[BR]]Where X refers to the superclass (and not the entity type). [[BR]][[BR]]Some examples that follow this structure:[[BR]][[BR]]·      CIRCULAR HOLLOW PROFILE - A hollow profile with two ends which has a constant circular hollow cross-section, except at the ends where it may have a special shape to support connection to other artefacts.[[BR]][[BR]]·      ALKALINE PUMP - A pump that is used for pumping alkaline liquids.x’[[BR]][[BR]]· CHRISTMAS TREE - An artefact that is an assembly of pipes and piping parts, with valves and associated control equipment that is connected to the top of a wellhead and is intended for control of fluid from a well.||||
||Submitting Organization|| The name of the company that has submitted the CR. ||||
||Submitter|| The name of an individual submitter. || ||
||label||The Label should be identical to the designation.||||


To pass the automatic verification new content must:
 * have a Part 2 !EntityType
 * have a superclass (to either an existing class in the PCA RDL or one of the newly proposed classes in the CR)
 * have a definition and designation for classes
