## Server Configuration
Your server should be configured to serve the following files from the
- provided `PUBLIC_DIRECTORY` in response to the following requests :—
+ provided `PUBLIC_DIRECTORY` in response to the following requests.
+For people using Caddy to serve their content, a sample `Caddyfile` is
+ included in this repository.
### H·T·M·L responses
+ **`GET /`**:
Serve the file at `/index.html`.
+ A `Link` header with the value
+ `</about.jsonld>;rel=meta;type="application/ld+json"` (or
+ equivalent) **must** be provided.
+
+ + **`GET /about`**:
+ Serve the file at `/.about.html`.
+ A `Link` header with the value
+ `</about.jsonld>;rel=meta;type="application/ld+json"` (or
+ equivalent) **must** be provided.
+ **`GET /statuses`**:
Serve the file at `/.statuses.html`.
In all cases, for `/$PATH.jsonld`, this just serves the file at
`/$PATH/index.jsonld`.
+ + **`GET /about.jsonld`**:
+ Serve the file at `/about/index.jsonld`.
+
+ **`GET /statuses.jsonld`**:
Serve the file at `/statuses/index.jsonld`.
The contents of this file **must** give the author’s URL,
optionally followed by a trailing newline.
+ + **`2=TITLE`** (where `TITLE` might be anything):
+ This file is **optional** and indicates the title of the status.
+ The value of `TITLE` **should** be a file·system‐friendly version
+ of the title, but is ignored.
+ The contents of this file **must** give the title of the status,
+ optionally followed by a trailing newline.
+
+ **`3=YYYY-MM-DD`** (where `YYYY-MM-DD` is a date):
This file is **required** and indicates the date of the status.
Only one date is currently supported.
## I Am Computer, How Do I Get Status?
-Assume you are given a U·R·L to a status collection, like `/statuses`,
- `/YYYY-MM`, or `/topics/my_topic`.
-Make a `HEAD` request to this U·R·L.
-If there is a `Link` header with a `rel` of `meta` and a `type` of
- `application/ld+json`, make a `GET` request to that U·R·L instead.
-Otherwise, make a `GET` request to the U·R·L you were given.
+Assume you are given a U·R·L `resource_url` which you think points to
+ some kind of Status.git resource.
+Start by resolving it as follows :—
+
+01. Make a `HEAD` request to `resource_url`.
+
+02. If there is a `Link` header with a `rel` of `meta` and a `type` of
+ `application/ld+json`, set `resource_url` to the URL provided in
+ that header and restart these steps from step 1.
+
+03. Make a `GET` request to `resource_url` and let `response` be the
+ response.
+
+04. Set `document` as follows :—
-Assuming the U·R·L you were given was valid, you will receive a
- Json‐L·D response with a `@type` which is either an
- `OrderedCollection` or an `OrderedCollectionPage`.
-One of the following will be true :—
+ 01. If the `Content-Type` header of `response` has a type of `text`
+ and subtype of `html`, let `document` be the result of
+ processing the body of `response` into a D·O·M tree as an
+ H·T·M·L document .
+ It is an error if this process fails.
- + The response is an `OrderedCollectionPage`.
- Its `items` will be an array of statuses, and the `prev` and
- `next` properties will give U·R·Ls for previous and next
- pages of statuses (if any exist).
+ 02. If the `Content-Type` header of `response` has a type of
+ `application` and a subtype which is `xml` or which ends in
+ `+xml`, let `document` be the result of processing the body
+ of `response` into a D·O·M tree as an X·M·L document .
+ It is an error if this process fails.
- + The response is an `OrderedCollection` with `first` and
- `current` properties.
- These properies give the U·R·Ls for the first and latest pages
- of statuses, which you can fetch and process as above.
+ 03. Otherwise, let `document` be null.
- + Otherwise, the `items` property will be an array of every
- status in the collection.
+05. If `document` is not null :—
- > If you receive a `Collection` instead of an `OrderedCollection`,
- > you are probably looking at a topics listing.
- > You will need to choose a topic from the `items` and then fetch it
- > to receive the list of statuses.
+ 01. If there is a `<link>` element in either the H·T·M·L namespace
+ or the Atom namespace in `document` with a `rel` of `meta`
+ and a `type` of `application/ld+json`, set `resource_url` to
+ the `href` of that `<link>` element and restart these steps
+ from step 1.
+ If multiple such elements exist, choose the first one.
+
+ 02. Otherwise, it is an error.
+
+06. If the body of `response` is not a Json document, it is an error.
+
+Assuming the U·R·L you were given was valid, you will end this
+ algorithm with a Json‐L·D response, and you can use the `@type`
+ attribute to determine the response type.
+`@type` will be either a string or an array.
+
+ + If the `@type` is or contains `Forum`, the resource is a collection
+ of topics.
+
+ + If the `@type` is or contains `Thread`, the resource is a
+ collection of statuses.
+
+ + If the `@type` is or contains `Microblog`, the resource describes
+ this site as a whole.
+ The `streams` property will contain a list of available `Forum`s
+ and `Thread`s, as objects with an `@id` and `@type`.
+
+The items in the collection (`Forum` or `Thread`) may be determined
+ through one of the following methods :—
+
+ + If the `@type` is or contains `CollectionPage` or
+ `OrderedCollectionPage`, then its `items` will contain resources.
+ This is a partial collection, and the `prev` and `next` properties
+ can be used to access further items from the parent collection
+ (indicated by `partOf`).
+ `first` and `current`, in this scenario, point “horizontally” to
+ the first and latest pages of items, not to subpages.
+
+ + If the `@type` is or contains `Collection` or `OrderedCollection`
+ and the resource has `first` and/or `current` properties, then
+ the `items` property will not be present.
+ `first` and `current` can be accessed to provide
+ `OrderedCollectionPage`s listing the items of the collection.
+
+ + Otherwise, the `items` property will contain every item in the
+ collection.
Statuses themselves have the following properties :—
+ **`@id`**:
The identifier of the status.
+ + **`@type`**:
+ The value `MicroblogPost`.
+
+ **`created`** [`dcterms:created`]:
The creation date for the status, as an `xsd:dateTime`.
