Part A is to be completed once per evaluator per comment submission.  Please

 2. Submission: OGC Request 35: OpenGIS(r) Catalogue Services Specification
2.0.1 (with Corrigendum) - ISO Metadata Application Profile (CSW2 AP ISO):
Request for Public Comments  


 PART B 
 ------ 
 1. Specification Section number: [Annex C]

 2. Criticality: [MAJOR] 

 3. Comments/justifications for changes: [COMMENTS, SUGGESTIONS] 

    The WSDL file can not be valided using  XMLSpy 2006 Enterprise Edition:

     In the ApIso-interfaces.wsdl, at line

       <xsd:import namespace="http://www.opengis.net/cat/csw"
schemaLocation="../csw2.0.1/CSW-publication.xsd"/>

    It generates the following error message:

    The target namespace 'http://www.opengis.net/cat/csw' of the <import>
definition must differ from  namespace

   'http://www.opengis.net/cat/csw'  of the enclosing schema.

   Can you publish the WSDL file that can be validated by recent version of
popular XML tools ?

 

PART B 
 ------ 
 1. Specification Section number: [8.2.2.1.2] Response

 2. Criticality: [MAJOR] 

 3. Comments/justifications for changes: [COMMENTS, SUGGESTIONS] 

    The two following sentences are confusing:

"The actual records returned by the catalogue are a substitute of the
element <csw:AbstractRecord>.... "

and then after

"Catalogue services implementing this application profile MUST NOT
substitute <csw:AbstractRecord> but rather <xs:any> with XML documents that
comply with one of the schemas defined in Annex D "

Can you explain the specific purpose of these two fields in the choice : 

<xsd:choice>

          <xsd:element ref="csw:AbstractRecord" minOccurs="0"
maxOccurs="unbounded"/>

          <xsd:any namespace="##other" processContents="strict"
minOccurs="0" maxOccurs="unbounded"/>

</xsd:choice>

 

PART B 
 ------ 
 1. Specification Section number: [8.2.2.1.2] Response  & 8.4.3

 2. Criticality: [MAJOR] 

 3. Comments/justifications for changes: [COMMENTS, SUGGESTIONS] 

   [8.2.2.1.2] Response   

   What do we do if in our existing catalogues we have metadata fields which
can not fit in the current schemas definitions  "MD_Metadata_Type" in Annex
D. 
    Is there an extension/customization  mechanism foreseen to allow to add
new fields or customize Metadata definitions to better fit with specific
catalogue needs ? 
    That seems to be suggested by the sentence:  "<SearchResults> element is
a generic XML container".
    Can we then replace the schema in annex D by ours ? following which
constraints ?
    Regarding [8.4.3], it seems that what annex D provides, are  examples
and not mandatory schemas.  
    Can you clarify what should be the approach to make an existing
catalogue CSW 2.0 ISO compliant ?
