+ <sioc:content rdf:parseType="Markdown"><![CDATA[
+As [recent conversations regarding a·i][satsuma:25796] and [racism in
+fandom][end_otw_racism] continue to exert pressure on the idea that the
+[Organization for Transformative Works][OTW] is in any way a good
+steward of the 11 million fanworks on their website [<cite>Archive of
+Our Own</cite>][AO3], some fans are again beginning to wonder if a
+centralized repository controlled by a single organization is truly the
+best solution for a community as diverse as fandom.
+
+There are a few reasons why one might say it is, but in this post I
+want to confront one: tagging. Tags (short labels which have been
+“wrangled” and organized into a hierarchial concept scheme) are the
+life·blood of search, filtering, and discovery on <cite>A·O·3</cite>,
+and powering this system is a huge cadre of volunteers whose duty it is
+to ensure that each label an author assigns to their work is organized
+correctly. <cite>A·O·3</cite>’s tagging system isn’t perfect—far from
+it—but the fact remains that a small, independent fan repository is
+unlikely to ever be able to muster the level of volunteer effort needed
+to build a tagging system of comparable utility. So, the argument goes,
+posting works to <cite>A·O·3</cite> is, at the very least, a necessary
+evil.
+
+I think this argument suffers from a failure of imagination. Even if we
+agree on the premise that tag wrangling work is labour‐intensive and
+fannish needs are best accommodated by a large, centralized tag
+authority, there is absolutely no reason why that tag authority
+couldn’t be shared by multiple small, independent repositories instead
+of being entirely controlled by one big one. We just need a way to get
+the tags from point A to point B.
+
+This blogpost describes one such way. It uses [the <cite>Tagging</cite>
+vocabulary][Tagging] to describe and federate tags from one centralized
+authority—which could be a large, volunteer‐run tag‐wrangling service
+in the model of <cite>A·O·3</cite>—out to potentially infinite
+independent repositories. It’s not necessarily a complete solution, and
+it’s unlikely that a system built with these technologies would work
+exactly like things do at <cite>A·O·3</cite>—but this is not
+necessarily a bad thing.
+
+## Tag Model
+
+The <cite>Tagging</cite> vocabulary is an R·D·F ontology, which is to
+say it is a collection of terms and definitions which might be used to
+convey information between computers on the Web. It’s not a syntax or
+a protocol, although the conventions of the present day dictate that
+this information should probably be conveyed in [J·son‐L·D][JSON-LD]
+via normal H·T·T·P·S `GET` requests. A tag might look as follows :—
+
+```json
+{ "@context": "https://ns.1024.gdn/Tagging/context.jsonld"
+, "@id": "https://ladys.example/tag:ladys.example,2023-05-23:5NJ-8SKG"
+, "@type": "SexualRelationshipTag"
+, "prefLabel":
+ { "literalForm":
+ { "@value": "Shadow × O·C"
+ , "@language": "en" } }
+, "altLabel":
+ { "literalForm":
+ { "@value": "Sexual Relationship: Shadow the Hedgehog & Original Character"
+ , "@language": "en" } }
+, "involves":
+ [ "https://ladys.example/tag:ladys.example,2023-05-23:N54-M773"
+ , "https://ladys.example/tag:ladys.example,2023-05-23:V2G-36D8" ] }
+```
+
+This object describes the tag
+`tag:ladys.example,2023-05-23:5NJ-8SKG`—or, as humans might refer to
+it, ‹ Shadow × O·C ›. It is a sexual relationship tag involving two
+other tags (`tag:ladys.example,2023-05-23:N54-M773` and
+`tag:ladys.example,2023-05-23:V2G-36D8`—presumably ‹ Shadow › and
+‹ Original Character ›), and it has both a preferred label and an
+alternate one provided. If `ladys.example` were a real tag authority
+and this were a real tag, any repository would be able to fetch this
+U·R·L and retrieve the tag, its label, and its relationships.
+
+If <cite>A·O·3</cite> provided this kind of service, we could begin
+building fanfiction repositories which leveraged their tagging system
+*today*.
+
+## Works and Tag Labels
+
+Of course, simply having dereferencable tags on the internet is only
+half of the struggle. We also need a means of associating them with
+works. In the <cite>Tagging</cite> vocabulary, this happens through a
+layer of indirection, because the labels that authors provide often do
+not match up exactly with the tag authority’s preferred labels for the
+tag. The way this works is as follows :—
+
+- The work itself *has a tag label collection*, probably an ordered
+ one.
+
+- This tag label collection then *contains tag labels*, which provide
+ the author‐assigned labels attached to the work.
+
+- Labels may then *label* a specific tag, linking to the formal
+ definition of the tag in some authority.
+
+How this all gets actually managed in practice is up to the repository
+in question; it’s certainly possible to use tags with a simpler (or
+more complex) model than this, and questions of how works *themselves*
+might get federated is a bit out·of·scope for this discussion. However,
+my own immediate target is building an [Atom feed][RFC4287] of
+fanfiction I’ve written; in this case, the tags might be added using
+[AtomTriples][draft-nottingham-atomtriples-00] like so :—
+
+```xml

+ </t:TagLabel>
+ </t:hasTagLabelList>
+ </t:hasTagLabelCollection>
+ </at:md>
+ </entry>
+</feed>
+```
+
+Note how each `<t:TagLabel>` above has an `@xl:literalForm` which
+supplies the author‐provided tag label, while also labelling an R·D·F
+resource which gives the canonical tag. This is obviously quite verbose
+(by nature of being X·M·L), and more sophisticated solutions will
+doubtless be developed in the future, but it is already good enough to
+start building things on top of.
+
+## Pulling in Tags
+
+Simply having the ability to fetch tags on request is likely
+insufficient for complex tagging systems or large repositories. A tag
+authority could have thousands of tags, and a repository needs to be
+able to not only discover them all but also keep them up·to·date
+without individually fetching each one. Inspired by the [<cite>I·I·I·F
+Change Discovery A·P·I</cite>][IIIF-Discovery], the current plan is to
+provide tag authorities with an [ActivityStreams][] event log which
+chronicles their changes, which repositories can then pull to update
+their models. The creation of a new romantic relationship tag
+`tag:ladys.example,2023-05-23:$BF-7607` might look like this :—
+
+```json
+{ "@context": "https://ns.1024.gdn/Tagging/discovery.context.jsonld"
+, "type":
+ [ "TagActivity"
+ , "Create" ]
+, "context": "https://ladys.example/tag:ladys.example,2023-05-23:"
+, "object": "https://ladys.example/tag:ladys.example,2023-05-23:$BF-7607"
+, "endTime": "2023-05-23T19:33:33-07:00"
+, "label": "Add Shadow ❤ O·C tag"
+, "comment": "This is the romantic equivalent of the existing (sexual) Shadow × O·C tag."
+, "states":
+ [ { "predicate": "a"
+ , "object": "RomanticRelationshipTag" }
+ , { "predicate": "prefLabel"
+ , "object":
+ { "@value": "Shadow ❤ O·C"
+ , "@language": "en" } }
+ , { "predicate": "involves"
+ , "object": "https://ladys.example/tag:ladys.example,2023-05-23:N54-M773" }
+ , { "predicate": "involves"
+ , "object": "https://ladys.example/tag:ladys.example,2023-05-23:V2G-36D8" } ] }
+```
+
+A change in the preferred label of that tag might look as follows :—
+
+```json
+{ "@context": "https://ns.1024.gdn/Tagging/discovery.context.jsonld"
+, "type":
+ [ "TagActivity"
+ , "Update" ]
+, "context": "https://ladys.example/tag:ladys.example,2023-05-23:"
+, "object": "https://ladys.example/tag:ladys.example,2023-05-23:$BF-7607"
+, "endTime": "2023-05-23T19:34:20-07:00"
+, "label": "Add variation selector 15 after heart"
+, "comment": "Helps to prevent emojification on mobile platforms."
+, "unstates":
+ [ { "predicate": "prefLabel"
+ , "object":
+ { "@value": "Shadow ❤ O·C"
+ , "@language": "en" } } ]
+, "states":
+ [ { "predicate": "prefLabel"
+ , "object":
+ { "@value": "Shadow ❤\uFE0E O·C"
+ , "@language": "en" } } ] }
+```
+
+In each case note that the activity `unstates` and `states` various
+triples, with the `subject` of each assumed to be the same as the
+`object` of the activity. As these are published in an chronological,
+paginated list, it is easy for consumers to skip activities that they
+have seen before. And because each activity identifies as its `object`
+the tag being changed, they can easily skip activities for tags they
+don’t care about, too.
+
+## Implementation Plans
+
+I’m currently working on a library for processing tag streams and a
+command‐line tool for generating them. Because this is a pull‐based
+model, it should be pretty easy to get a proof‐of‐concept up that is
+backed by static files and a minimal Caddy configuration. Then I will
+attempt to create a simple web viewer for browsing the tags, as well as
+start publishing works which use them. I’ll be sure to post updates to
+this blog when·ever any of this happens!
+
+A lot of the initial discussion for this work has taken place on the
+[Fandom Coders][Fancoders] Discord server. Shoutout to the people there
+for putting up with my many 4 A·M Freeform diagrams and rants about
+ActivityStreams.
