It owns **representation** and nothing else: a transformer registry, the URIs objects and collections are named by, and the single renderer that writes the JSON. What a thing _is_ stays with the plugin that stores it; this decides how it is described to a reader that speaks ActivityStreams. **This plugin needs Axismundi Actors.** It resolves the identities an object names— its author, the accounts it mentions, the Actor documents it serves — and without that registry there is nobody for any of them to refer to. **Axismundi Activities is optional, and adds four things.** Without it a published post is public and is projected as such, which is this plugin’s own default. With it, the four authored visibility levels decide who a post is addressed to, an Actor’s outbox and follow collections have contents rather than being empty, an object states who may quote it, and an object says who published it. Nothing here breaks when it is absent; less is said. That last one is worth stating plainly: who an object is attributed to is decided by whatever recorded its publication, not derived here from the WordPress author. An object nobody has published has no `attributedTo` — it is readable, it simply was not published by anyone. #### What this version does * **Content negotiation on the URL a post already has.** Ask for application/activity +json and the same address answers with JSON-LD instead of HTML. * A **Core Post to Article transformer**, and an optional adapter for Axismundi Media Library attachments. * **A post’s own media**, listed as attachments so a reader can fetch what the body shows: the featured image and the media blocks the author placed. Only media this site holds — a hotlinked image is left in the text, because its type and size cannot be stated. * **Collections**: an Actor’s outbox, followers and following, a shared media folder at a stable UUID route, and a replies collection. An Actor document always names them; without an Activity ledger they answer empty rather than 404. * The **relations that make a document readable in context** — hashtags, mentions, thread edges, reply context, and quote context — kept as their own records rather than parsed out of content each time. * A **remote object repository**: URI-keyed, rebuildable observations of objects this site has been told about, for administrators to inspect under **Tools > Remote Objects**. * An administrator can **probe a remote collection** and its first page without storing the collection, following its item URLs, or downloading anything binary. #### What this version does not do There is no Activity ledger, no inbox write handling, no Follow/Like/Announce state, no HTTP signatures, and no delivery. Those belong to Axismundi Activities and to the ActivityPub transport boundary. Nothing here signs or sends an Activity. #### Alongside the official ActivityPub plugin Both plugins negotiate the same canonical URLs, and two answers for one address is worse than either answer alone. So when the official ActivityPub plugin is active, this plugin’s standalone negotiator **turns itself off** and leaves those URLs to it, while the registry and renderer stay available. Nothing here overrides or replaces that plugin’s object ids. #### What is stored about other people’s documents An observation of a remote object is a **cache, not a record**: it is keyed by the remote URI, which stays canonical, and it can be rebuilt by fetching again. Observations expire, and a scheduled daily task deletes the expired ones along with anything left pointing at them. Remote media is **never downloaded and never hotlinked**. A cached object’s attachments are described — type, size, the text the author wrote about them — and not fetched. Where a cached object is shown locally at all, it is shown `noindex`, only for objects that were addressed publicly, and only as a courtesy view beside the remote original. ### External services This plugin reads documents from other websites. Every request is a `GET` made through wp_safe_remote_get(): redirects are not followed automatically, the response size is capped, and any address inside your own network is refused. Nothing about your site’s content or your users is sent as data. As with any outgoing HTTP request the server being contacted receives **your site’s IP address**, and a `User-Agent` header naming this plugin, its version, and **your site’s home URL**. Requests happen for two reasons, and the second is worth being clear about. **Because an administrator asked.** * **Fetching one remote object.** Under **Tools > Remote Objects**, an administrator can fetch the address of an ActivityStreams object to inspect it. What is read is that one JSON document; what is stored is its metadata — tags, mentions, audience, attachment descriptors, extension properties, and the payload itself, escaped. * **Probing a remote collection.** An administrator can read a collection and its first page from the same host to see what it contains. The collection is not stored, its item URLs are not followed, and nothing binary is downloaded. **Because something arrived here naming an address.** * **Only if you switch it on.** Under **Tools > Remote Objects** there is a setting called _Background acquisition_, and it is **off** unless an administrator turns it on. While it is off this site contacts a remote server only when you ask it to on that screen. * With it on: when a publicly addressed `Announce` reaches this site’s inbox carrying only the URI of the object it announces, that one address is queued for a single background fetch, so that the announcement can be shown as something rather than as a link. The object’s author is looked up the same way if this site does not already know them. * Either way the request tells the remote host that this site exists, including its address and its IP, which is why the decision is the site owner’s and not a stranger’s. * This is deliberately bounded. It never runs while a page is being rendered, it does not fan out to the mentions or the audience named in the document, an address already known is not fetched again, and only `https` addresses are considered. Turning the setting off also clears anything already queued. Which servers are contacted therefore depends on which addresses your administrators enter and which sites send things to your inbox. This plugin has no service of its own and sends nothing to its author. Each server contacted is somebody else’s, run under its own terms of service and privacy policy. ## Blocs Aquesta extensió proporciona 17 blocs. * Interactions The row of interaction controls for the current Object. Holds Interaction blocks the way Core's Buttons holds Button, so alignment, gap, and justification work the same way. * Axismundi Question A Question's local voting controls or read-only results. * Object Card Body The part of an Object card that depends on what kind of Object it is: a Note's warned body, or an Article's lead image, title and summary. * Object Replies The public reply thread of the ActivityStreams Object being rendered, including replies received from other servers. * Object Content The body of the ActivityStreams Object being rendered, with its authored sensitive-content gate. The Object sibling of Core's Post Content. * Object Date The publication or modification date of the ActivityStreams Object being rendered. The Object sibling of Core's Post Date. * Object Content Warning Folds everything an authored content warning covers — body, quote, poll, and attachments — behind one disclosure, the way Mastodon and Misskey present a warned post. Without an authored warning it renders its blocks untouched. * Object Hashtags The shared hashtags of the ActivityStreams Object being rendered. The Object sibling of Core's Post Terms: same term links, but resolved for cached remote Objects as well as local ones. * Object Visibility Who the ActivityStreams Object being rendered was addressed to. Its audience, not where it was posted — being in a community is a separate fact. * Object Featured Image The lead image of the ActivityStreams Object being rendered, or the header image of the Actor in context. The Object sibling of Core's Featured Image, with Cover's overlay and focal-point controls. * Object Summary The explicit summary of the ActivityStreams Object being rendered. The Object sibling of Core's Post Excerpt: local Articles use content before the More block, or their authored excerpt when no More block exists; remote Objects use their authored summary. * Object Card Header The identity row an Object card opens with. Which Actor it names is decided by the surface the card is on. * Object Read More A link into the full representation of the ActivityStreams Object being rendered. The words are yours to write, the destination is the Object's. * Object Type The ActivityStreams type of the Object being rendered. The Object sibling of Core's Query Title. * Object Attachments The media attachments of the ActivityStreams Object being rendered. The Object sibling of Core's Gallery: same nested-image markup, columns, and crop behaviour, but the items come from a local or cached remote Object instead of the Media Library. * Object Title The title of the ActivityStreams Object being rendered. The Object sibling of Core's Post Title: it resolves a local or cached remote Object instead of the current WordPress post. * Quote Context A consent-aware embedded preview of the Object quoted by the current Object. ## Instal·lació 1. Install and activate **Axismundi Actors** first. This plugin projects identities from that registry and does very little without it. 2. Upload this plugin folder to `/wp-content/plugins/`, or install it through **Plugins > Add New**, then activate it. 3. Nothing else is required. A published post is projected straight away; ask its URL for application/activity+json to see the result. It carries no `attributedTo` until something records who published it. Add **Axismundi Activities** for that, and for the four authored visibility levels and an Actor outbox with activities in it, and the official **ActivityPub** plugin with **Axismundi ActivityPub Bridge** to send and receive. 4. Remote observations, where there are any, are listed under **Tools > Remote Objects**. Activation creates this plugin’s own database tables. Nothing is contacted on the internet during installation, and deactivation removes the scheduled tasks it added. ## Ressenyes No hi ha ressenyes per a aquesta extensió. ## Col·laboradors i desenvolupadors «Axismundi Object Projections» és programari de codi obert.

The stock post allowlist removes the `template` element and the Interactivity API directives, so it is not used here. * Body decoration filters run before sanitizing rather than after it, so nothing a filter adds can reach the page unsanitized. * Who an object is attributed to now comes from whatever recorded its publication instead of being derived from the WordPress post author. The two agree only while every account has one identity, and they stop agreeing as soon as anyone publishes as an organisation. * A post whose author has no Actor is projected and readable, without an `attributedTo`, rather than refused. It is not published to anyone. * The site Actor is no longer a fallback author. It is an application identity, not a person who writes posts. #### 0.1.1 * Background acquisition is now a setting, off by default. While it is off this site contacts a remote server only when an administrator asks it to under Tools > Remote Objects. Turning it off also clears anything already queued. * A post publishes its own media as attachments: the featured image and the media blocks the author placed, and only media this site holds. * A published post is projected with Axismundi Actors alone; an Actor document always names its outbox, followers and following, which answer empty without an Activity ledger. * A product can claim this projection for an object whose context it owns, instead of rebuilding it. Axismundi Forum publishes its Topics that way. * A quote of the author’s own post is recognised as approved, as FEP-044f allows, when both authors are known here. * Filtered card templates and interaction controls are now named blocks rather than markup, so what reaches the page is always something a registered block rendered. #### 0.1.0 * First release. * Content negotiation on existing WordPress object URLs, so a post’s own address answers with ActivityStreams JSON-LD when asked for it, and a transformer registry with a single renderer behind it. * A Core Post to Article transformer, and an optional adapter for Axismundi Media Library attachments. * Collections: shared media folders on a stable UUID route, a replies collection, and the representation of an Actor outbox where Axismundi Activities supplies one. * Hashtags, mentions, thread edges, reply context and quote context stored as their own records rather than re-derived from content. * A URI-keyed repository of remote object observations, with administrator inspection under Tools > Remote Objects and a remote collection probe that stores nothing. * Cached remote media is described and never downloaded or hotlinked; observations expire and are purged daily. * The standalone negotiator disables itself when the official ActivityPub plugin is active, so that one URL keeps one answer. ## Meta * Versió **0.1.2** * Darrera actualització **fa 1 dia** * Instal·lacions actives **Menys de 10** * Versió del WordPress ** 6.7 o posterior ** * Provada fins a **7.1.2** * Versió del PHP ** 8.1 o posterior ** * Idioma * [English (US)](https://wordpress.org/plugins/axismundi-object-projections/) * Etiquetes * [activitypub](https://ca.wordpress.org/plugins/tags/activitypub/)[ActivityStreams](https://ca.wordpress.org/plugins/tags/activitystreams/) [federation](https://ca.wordpress.org/plugins/tags/federation/)[jsonld](https://ca.wordpress.org/plugins/tags/jsonld/) * [Vista avançada](https://ca.wordpress.org/plugins/axismundi-object-projections/advanced/) ## Valoracions Encara no s'ha enviat cap ressenya.
