Postpone until DB and JL are back.

License for the samples

SP: It's been a long time since I reviewed the different licenses.

NV: The problem is that the GPL v3.0 license is viral.

Investigation reveals that SP committed the GPL V3 license when the repository was created.

<Steven> https://www.w3.org/copyright/document-license-2023/

<Steven> "Permission to copy, and distribute the contents of this document, or the W3C document from which this statement is linked, in any medium for any purpose and without fee or royalty is hereby granted, provided that you include the following on ALL copies of the document, or portions thereof, that you use:"

Some discussion of the problems associated with licensing.

NW: I think using the W3C Software and Document license makes sense.

Further discussion leads to ambiguity about whether or not a Community Group can use that license.

<Steven> https://www.w3.org/community/about/process/summary/

<Steven> Here is the license agreement: https://www.w3.org/community/about/process/cla/

SP: But this is only for contributors who have joined the group.

NW: We could just make the samples CC0.

SP: Shall we?

BTW: Yes.

NV: Yes.

ACTION: 2025-10-14-c NW to update the README in the samples to make them CC0 explicitly.

ACTION: 2025-10-14-d SP to reply to Alain.

Review of materials for the proposed symposium

SP: We want to get the announcement out soon.

Some discussion of deadlines and timelines.

SP: Should we make the deadline 15 December?

Consensus: Yes.

NW: SP made some suggestions in email.

Consensus: make the symposium page a single page, don't have a separate page for the CFP.

Some discussion of "Invisible XML" versus "Invisible Markup"

NW: I prefer Invisible XML in the title for visibility.

SP: I'd like "Invisible Markup" in the description somewhere.

BTW: I don't think "Invisible Markup" is an established term. It may be confusing if we use it here without first establishing it.

SP: I'm not sure. We created the group as an "Invisible Markup" group.

Some discussion of "markup" vs "XML" in this context.

Consensus: NW will update the pages with his best effort and then we'll publish them.

SP: Where are we going to announce: Slack, LinkedIn, Facebook, XML-related mailing lists. Mastodon, our weblogs.

SP: I'll make a LinkedIn page and an event on Facebook.

SP: What mailing lists.

BTW: Ours!

NV: We can announce it as Declarative Amsterdam.

SP: I'll do LinkedIn and Facebook.

NW: I'll Slack, and our mailing list.

NV: I'll send something to XML.com.

<Steven> https://invisiblexml.org/1.0/ixml.xml

ACTION: 2025-10-14-e NW to fix the iXML grammar link on the home page.
