6、ds bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organi
7、zations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in
8、 the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 %
9、of the member bodies casting a vote. In other circumstances, particularly when there is an urgent market requirement for such documents, a technical committee may decide to publish other types of document: an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical ex
10、perts in an ISO working group and is accepted for publication if it is approved by more than 50 % of the members of the parent committee casting a vote; an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical committee and is accepted for publication if it
11、is approved by 2/3 of the members of the committee casting a vote. An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is confirmed, it is rev
12、iewed again after a further three years, at which time it must either be transformed into an International Standard or be withdrawn. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying

ISO 19135 consists of the following parts, under the general title Geographic information Procedures for item registration: Part 2: XML schema implementation Technical Spec
14、ification A part 1 dealing with procedures for item registration is under preparation. iv ISO 2012 All rights reserved ISO/TS 19135-2:2012(E) Introduction The ISO 19135 series standardizes the procedures for the registration of geographic items. Since it does not provide any encoding for the storage
15、 and exchange of registers and register items, implementations may vary based on the interpretation of the base standard. This Technical Specification defines an XML encoding for the storage and exchange of ISO 19135-compliant registers and register items. This encoding conforms to the rules describ
16、ed in ISO/TS 19139. The encoding defined in this Technical Specification is intended to be extended to specific registers, e.g. ISO 19145 1)for registers of representations of geographic point location. 1) To be published.

18、 Annex A and all the relevant tests specified in Annex A of ISO/TS 19139:2007.

23、 This XML schema implementation of ISO 19135 follows the encoding rules stated in ISO/TS 19139:2007, Clause 8. The exceptions and the implementations based on external types are detailed in this clause. This clause uses the UML notation commonly used in ISO geographic information standards and the s
24、pecific notations defined in ISO/TS 19139:2007, 5.4. In the list below, the item on the left describes the common namespace prefix used to describe the elements in the namespace. The second item is a description in English of the namespace prefix, and the item in parentheses is the URI of the actual

29、O 19135:2005. The UML classes defined in ISO 19135:2005, 8,2 and 8.7 to 8.24, are implemented in XML schema following the encoding rules defined in Clause 8 of ISO/TS 19139:2007. These classes are: RE_Register, RE_ReferenceSource, RE_RegisterItem, RE_ProposalManagementInformation, RE_AdditionInforma
30、tion, RE_ClarificationInformation, RE_AmendmentInformation, RE_Reference, RE_SubregisterDescription, RE_AlternativeExpression, RE_AlternativeName, RE_Locale, RE_Version, RE_FieldOfApplication, RE_ItemStatus, RE_DecisionStatus, RE_Disposition, RE_AmendmentType and RE_SimilarityToSource. Additionally,
31、 this XML schema contains two customized encodings, described in 8.3.2 and 8.3.3. 8.3.2 RE_RegisterOwner, RE_RegisterManager, and RE_SubmittingOrganization An abstract element grg:AbstractRegisterStakeholder of type grg:AbstractRegisterStakeholder_Type is created to share the two common attributes o

35、RegisterOwner, RE_RegisterManager and RE_SubmittingOrganization 8.3.3 RE_ItemClass ISO 19135:2005, 8.6.6, states that the Categorization association between RE_RegisterItem and RE_ItemClass shall be navigable from describedItem to itemClass but need not be navigable in the other direction. However,
36、communities implementing ISO 19135 have identified a requirement to navigate from itemClass to describedItem. Since it is not prohibited by ISO 19135, this Technical Specification defines an encoding for describedItem as a role of RE_ItemClass. The XCT of RE_ItemClass contains an XML schema element

39、d ISO/TS 19135-2:2012(E) Annex A (normative) Abstract test suite A.1 Introduction This Technical Specification defines an XML schema encoding compliant with ISO/TS 19139. As such, this abstract test suite includes, by reference, the abstract test suite specified in ISO/TS 19139. A.2 Overview of conf
40、ormance test tools Minimum conformance with this Technical Specification requires that geographic register and register item instance (XML) documents can be validated without error against the XML schemas defined by the encoding rules in Clause 8 of ISO/TS 19139:2007 and described in detail in Claus
41、e 8 of this Technical Specification. While many tools are available to test validation of XML instance documents against provided XML schemas, it is important to understand that not all validation tools implement the full W3C XML schema recommendation and not all validation tools interpret the W3C X
42、ML schema recommendation in the same manner. It is recommended that a tool with strict interpretation of XML schema and full support for the W3C XML schema recommendation be used to ensure conformance. A.3 Conformance requirements Constraints XML schema 1.0 does not support the enforcement of certai
43、n types of constraints. For example, co-constraints such as the requirement that a register item with a “notValid” value on the “status” attribute implies a “notEmpy” value for the “dateAccepted” attribute cannot be enforced with XML schema. Document schema definition languages other than XML schema
44、, e.g. Schematron or XSLT 2.0, should be used to implement these constraints. As a result, it is imperative that implementers heed the anchor notes shown in the figures of ISO 19135. Table A.1 shows the affected elements and the anchor notes and annotations. ISO 2012 All rights reserved 5 ISO/TS 191
