XSDs with duplicated declaration of types

[Intelligent2013]

Some XSDs have duplicated declaration of types (via xsd:import). For example, 19115/-3/mda/1.0/mda.xsd: Error:

File http://standards.iso.org/iso/19115/-3/gco/1.0/baseTypes2014.xsd has errors.
        'gco:AbstractObject_Type' is already declared.
in schems: https://schemas.isotc211.org/19115/-3/gco/1.0/baseTypes.xsd

List of XSDs with such issue:

• ~19115/-3/mda/1.0/mda.xsd~ (ignore issue, because there is version 2.0)
• ~19115/-3/mda/1.0/metadataApplication.xsd~ (ignore issue, because there is version 2.0)

This is blocking ISO-TC211/schemas.isotc211.org#18.

@Intelligent2013 can you help fix these with a PR? Thanks.

In XSDs there are 3 types of links to another XSDs:

1. relative path:

   <xs:import namespace=... schemaLocation="../../../../19103/-/gco/1.2.0/gco.xsd"/>

2. absolute path to https://schemas.isotc211.org:

   <import namespace=... schemaLocation="https://schemas.isotc211.org/19115/-3/gco/1.0/gco.xsd"/>

3. absolute path to http://standards.iso.org:

   <import namespace=... schemaLocation="http://standards.iso.org/iso/19115/-3/gco/1.0/gco.xsd"/>

As I understand, types 1 and 2 are equal, because https://schemas.isotc211.org is a mirror of this repository.

Regarding type 3, as soon XSD opens any another XSD from site http://standards.iso.org, then all paths evaluate from http://standards.iso.org, not from https://schemas.isotc211.org (or local disk). Between https://schemas.isotc211.org and http://standards.iso.org there is difference, for example:

• in schema https://schemas.isotc211.org/19115/-3/gco/1.0/gco.xsd:

  <xs:include schemaLocation="baseTypes.xsd"/>

• in schema https://standards.iso.org/iso/19115/-3/gco/1.0/gco.xsd:

  <xs:include schemaLocation="baseTypes2014.xsd"/>

What is difference between https://schemas.isotc211.org and https://standards.iso.org? Can we replace all links to https://schemas.isotc211.org?

[ejbleys]

Will deal later today Type 3 should not exist ...2014 exists because it did - should continue

this is probably round tripping - that is allowed name=“AbstractObject_Type” is declared in https://schemas.isotc211.org/19103/-/gco/1.2.0/baseTypes.xsd https://schemas.isotc211.org/19115/-3/gco/1.0/baseTypes.xsd https://schemas.isotc211.org/19115/-3/gco/1.0/baseTypes2014.xsd https://schemas.isotc211.org/19139/-/gco/1.0/gcoBase.xsd There is no direct or indirect interactions between these files

Type 1 could be converted into type 2 if you prefer There are pros and cons for each

@ejbleys for type 3, the only issue here is with schemaLocation. Why don't we change all the https://standards.iso.org/... to https://schemas.isotc211.org/...? It doesn't affect the namespace or the usage of the schema. schemaLocation in any case is technically provided as an informative hint.

@ejbleys I can't see the GH update, was it pushed? Thanks.

[Intelligent2013]

this is probably round tripping - that is allowed name=“AbstractObject_Type” is declared in https://schemas.isotc211.org/19103/-/gco/1.2.0/baseTypes.xsd https://schemas.isotc211.org/19115/-3/gco/1.0/baseTypes.xsd https://schemas.isotc211.org/19115/-3/gco/1.0/baseTypes2014.xsd https://schemas.isotc211.org/19139/-/gco/1.0/gcoBase.xsd There is no direct or indirect interactions between these files

@ejbleys yes, between these files there isn't interactions directly. But via another XSDs we get the case, when:

• one imported XSD (let's say "A") pointed to baseTypes.xsd, and
• another imported XSD (let's say "B") pointed to baseTypes2014.xsd
• 19115/-3/mda/2.0/mda.xsd pointed to "A" XSD and "B" XSD, i.e. 19115/-3/mda/2.0/mda.xsd imported both "baseTypes.xsd" and "baseTypes2014.xsd", and we get duplicated declarations.

I've checked my proposal (change http://standards.iso.org/ to https://schemas.isotc211.org/) on a few above noticed xsd, and the issue was gone.
