Fix `schemaLocation` paths that points to non-existing paths on standards.iso.org

[ronaldtse]

In #24 it is now known that some schema files on standards.iso.org have been deleted.

We need to update existing schema files in our repo to no longer point there but to a local copy.

Opinions please (Not just Ron and Evert) Local copy? ie relative path Only works in situ OR schemaLocation =“https://schemas.isotc211.org/ https://schemas.isotc211.org/…”?

For those who need to see what it would look like Here is a ZIP file containing ISO 19139 and ISO 19136 in the directory structure as discussed using relative paths

Note: I have not tried to include ISO 19119 In the XML (.xml & .xsd), I have not changed anything but the schema locations and the layout of the namespace attributes

Whatever you do, don't include any copy of 19136 / GML schema documents on schemas.isotc211.org. Just reference the normative schemas in the OGC schema repository where OGC has policies and processes in place to maintain permanent availability and include bugfixes as needed. Everything else are broken or outdated copies like the ones previously on standards.iso.org.

Thanks Will do I’ll look for the appropriate schema locations Cheers Evert

As Clemens says, where we are importing schemas that are managed by other groups, we should reference them at their URLs. I think the same principle could be usefully applied where on TC211 standard imports a schema from another TC211 standard. In my view, relative paths are for where the package/schema file being imported is part of the same standard.

Of course, that gives some ambiguity for ISO 19136 / GML - but that is resolved by the Foreword & informative annex C of 19136-1 stating that the schemas are at http://schemas.opengis.net/gml/3.2.1/ (in 19136:2007 it's "only" in the Annex and examples). So (as you'd expect) Clemens is correct.

But as I've said on the other issues & pull requests that refer to this issue, there are many people "out there" who refer to the standards.iso.org locations that have worked for many years.

It's one thing to ensure that we have our own copy safely tucked away, but it is more urgent for our users to work with ISO to get them to reinstate the resources they have removed. Or if that is a strategic refusal (rather than a mistake), to work with us to communicate the change to a large existing user base - or else take a real hit to their credibility for managing IT resources.

I have emailed Mats asking him to contact them.

Hi, we are implementing ISO 19115-2:2019-01. And face the same problem: the spec indicates that the online schema is availalbe on https://standards.iso.org/iso/19115/-2/gmi/ however if we use these, our INSPIRE metadata files doesn't validate due to the missing schema locations at http://standards.iso.org/ittf/PubliclyAvailableStandards/ISO_19139_Schemas/

For us it is necessary to solve this quickly. Any idea how to cope with this in the short term?

Many Thanks! Martine Paepen (VITO / Belgium)

[ronaldtse]

Looks like this is no longer an issue since 19139 has returned? @ejbleys please feel free to close if it is the case. Thanks!

[PeterParslow]

@ronaldtse , where has it returned to? It's not at the "previously most authoritative place", https://standards.iso.org/ittf/PubliclyAvailableStandards/ISO_19139_Schemas/

If https://standards.iso.org/iso/19139/ is now considered the right place, then there are still schema import issues to solve (both for TC211 and others - INSPIRE, OGC,...)

[ronaldtse]

@PeterParslow bad wording on my part. It has been "re-inserted" (commit: 842920a533e7b8ddd8a95c95a6a3bb6f373f6ace) to schemas.isotc211.org .

This issue was originally meant to address missing schemaLocations sent out to standards.iso.org.

If https://standards.iso.org/iso/19139/ is now considered the right place, then there are still schema import issues to solve (both for TC211 and others - INSPIRE, OGC,...)

This still applies...

[ronaldtse]

I did a search in the repo, and these schemaLocations are no longer around:

http://standards.iso.org/ittf/PubliclyAvailableStandards/ISO_19136_Schemas/gml.xsd (point to http://schemas.opengis.net/gml/3.2.1/ ?)

http://standards.iso.org/ittf/PubliclyAvailableStandards/ISO_19139_Schemas/gco/gco.xsd http://standards.iso.org/ittf/PubliclyAvailableStandards/ISO_19139_Schemas/gmd/gmd.xsd http://standards.iso.org/ittf/PubliclyAvailableStandards/ISO_19139_Schemas/gmx/gmx.xsd

We should probably update these to reflect the new resolvable location.

And we should have a place on the website to show where the authoritative schemas are located to prevent user confusion!

[ejbleys]

Hi Guys The only authoritative space is https://schemas.isotc211.org https://schemas.isotc211.org/

Note: the same problem also affects the schemaLocation attributes in the code lists e.g. https://schemas.isotc211.org/schemas/19139/resources/gmxCodelists.xml - which are ours to fix.

[ejbleys]

These now, appropriately, reside in https://schemas.isotc211.org/19139/-/ https://schemas.isotc211.org/19139/-/ Cheers e Evert Bleys 4 Tudor Place HUGHES ACT 2605 Australia +61 (0)2 62811773 +61 (0)411 483 876 ejbleys@gmail.com Skype ejbleijs@gmail.com

@ejbleys OK - but why do we also host a set with the unhelpful schemaLocations, at the URL I gave?

After I posted this, Mats let me know that ISO have redirected the old 19139 location on their site to https://standards.iso.org/iso/19139/

[ejbleys]

Hi Peter I see what you mean Anyone on the XMG is at liberty to help fix them

ISO 19136 has been retired use GML The ISO 19139 XSDs were lost, once they were recovered, they have been extracted, schemaLocations adjusted and placed into the agreed location The appropriate location for those XSDs are: https://schemas.isotc211.org/19139/-/gmd/1.0/gmd.xsd https://schemas.isotc211.org/19139/-/gmd/1.0/gmd.xsd https://schemas.isotc211.org/19139/-/gmd/1.0/gmd.xsd https://schemas.isotc211.org/19139/-/gmd/1.0/gmd.xsd https://schemas.isotc211.org/19139/-/gmx/1.0/gmx.xsd https://schemas.isotc211.org/19139/-/gmx/1.0/gmx.xsd
