# SocialCG Issue Triage Present: - Evan Prodromou - Bob Wyman - Dmitri Zagidulin - Ted Thibodeau - a - Emelia Smith ## Activity Streams 2.0 issues ### Document Versioning Process https://github.com/w3c/activitystreams/issues/460 Discussion: - Dmitri: the contexts need to be versioned - Evan: What we have been doing is every change making a snapshot and saving that as a version. - Dmitri: We need to ensure we don't require a specific context value. - Dmitri: If we want to continue updating the main context with its stable URL, we need to be careful that updates don't break existing services. - Dmitri: The existing signatures mastodon and others are using are fetching the context document, therefore if the context changes the signature for the activity changes. (Specifically, if any of the existing terms in the context are changed, signatures will break. So, additive updates: no prob; Changing existing terms: no good.) Decision - Linked to primer document describing snapshot versioning & how to use the snapshot versions: https://www.w3.org/wiki/Activity_Streams/Primer/Context_document_versioning ### Example 146: Missing Z in startTime https://github.com/w3c/activitystreams/issues/445 Discussion: - Evan: Yes, it is missing a Z Decision: - Should be updated via Errata PR: https://github.com/w3c/activitystreams/pull/590 - Marked as needs group input decision ### Digital Signatures in ActivityPub documents This was an aside relating to the Document Versioning Process, there was a brief 5 minute discussion, which we decided to take to the [Mailing List](https://lists.w3.org/Archives/Public/public-swicg/2024Mar/0028.html) ### Other Issues We also reviewed and closed or commented on issues marked as ["Pending Closure Resolved"](https://github.com/w3c/activitystreams/issues?q=is%3Aopen+is%3Aissue+label%3A%22Pending+Closure+Resolved%22) When doing ActivityPub next week, we should consider the issues marked as ["Pending Closure 7 days"](https://github.com/w3c/activitypub/issues?q=is%3Aopen+is%3Aissue+label%3Apending-closure-in-7-days+)
