+# x_status_git
+
+A minimal git‐based microblog.
+
+## What It Is
+
+ +  A Python script, `post-receive`, suitable for use as a post‐receive
+      Git hook, which generates a number of `.jsonld` files from a
+      source repository of text posts.
+
+ +  A small collection of H·T·M·L files designed to display the
+      generated `.jsonld` in a human‐readable fashion.
+
+## What It Is Not
+
+ +  A server or server configuration (you will need to supply these
+      yourself; see below).
+
+ +  Suitable for deployment on a simple filesystem server like
+      NeoCities or GitHub Pages (it requires both Git hooks and H·T·T·P
+      routing).
+
+ +  Interactive in any way (i·e “social media”).
+
+ +  Compatible with the ActivityPub fediverse (or any other push‐based
+      social media platform).
+
+## Script Configuration
+
+You will need to edit the `post-receive` script to adjust the following
+  constants to match your setup :—
+
+ +  **`GIT_DIRECTORY`**:
+    The absolute path to this Git repository on your server.
+    It is expected that this will be a bare repository (ending in
+      `.git`).
+
+ +  **`BUILD_DIRECTORY`**:
+    In order to access the files when you push, the repository will be
+      checked out here.
+    **This directory will be deleted on every push.**
+
+ +  **`PUBLIC_DIRECTORY`**:
+    The directory that your server serves files from.
+    **This directory will be deleted on every push,** so if you need to
+      serve additional files (i·e those not generated by this script),
+      you should place those files in a different directory and adjust
+      your server configuration accordingly.
+    Note that the `post-receive` script and associted H·T·M·L files
+      provided by this repository expect a certain server configuration
+      described below.
+
+  +  **`PUBLIC_URL`**:
+     The U·R·L that you are serving your site from (with no trailing
+       slash).
+     You cannot serve Status.git from a subdirectory.
+
+A `Makefile` is provided to make installing the `post-receive` script
+  on your server easy (assuming you have `ssh` access).
+You’ll need to supply some variables there, too :—
+
+ +  **`USERNAME`**:
+    Your SSH username.
+
+ +  **`DOMAIN`**:
+    The domain or other address of your site.
+
+ +  **`GIT_REPOSITORY`**:
+    The absolute path to this Git repository, as above.
+
+## Server Configuration
+
+Your server should be configured to serve the following files from the
+  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
+
+These responses **must** be served with a `Content-Type` of
+  `text/html;charset=UTF-8` (or equivalent).
+Note that these paths **do not** have a trailing slash.
+
+ +  **`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`.
+    A `Link` header with the value
+      `</statuses.jsonld>;rel=meta;type="application/ld+json"` (or
+      equivalent) **must** be provided.
+
+ +  **`GET /statuses/$YYYY-MM`** (where `$YYYY-MM` is an `xsd:gYearMonth`):
+    Serve the file at `/.topic.html`.
+    A `Link` header with the value
+      `</$YYYY-MM.jsonld>;rel=meta;type="application/ld+json"` (or
+      equivalent) **must** be provided.
+
+ +  **`GET /statuses/$YYYY-MM/*`** (where `$YYYY-MM` is an `xsd:gYearMonth`):
+    Serve the file at `/.status.html`.
+    A `Link` header with the value
+      `</$YYYY-MM.jsonld>;rel=meta;type="application/ld+json"` (or
+      equivalent) **must** be provided.
+
+ +  **`GET /topics`**:
+    Serve the file at `/.topics.html`.
+    A `Link` header with the value
+      `</topics.jsonld>;rel=meta;type="application/ld+json"` (or
+      equivalent) **must** be provided.
+
+ +  **`GET /topics/$TOPIC`** (where `$TOPIC` matches `[0-9A-Za-z_-]+`):
+    Serve the file at `/.topic.html`.
+    A `Link` header with the value
+      `</$TOPIC.jsonld>;rel=meta;type="application/ld+json"` (or
+      equivalent) **must** be provided.
+
+ +  **`GET /topics/$TOPIC/*`** (where `$TOPIC` matches
+      `[0-9A-Za-z_-]+`):
+    Serve the file at `/.status.html`.
+    A `Link` header with the value
+      `</$TOPIC.jsonld>;rel=meta;type="application/ld+json"` (or
+      equivalent) **must** be provided.
+
+### X·H·T·M·L responses
+
+These responses **must** be served with a `Content-Type` of
+  `application/xhtml+xml` (or equivalent).
+Note that these paths **do not** have a trailing slash.
+
+ +  **`GET /$IRI`** (where `$IRI` contains a colon and no slash):
+    Serve the file at `/.lookup.xhtml`.
+    This can be used to look up statuses by their identifier.
+
+### Json‐L·D responses
+
+These responses **should** be served with a `Content-Type` of
+  `application/ld+json`.
+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`.
+
+ +  **`GET /statuses/$YYYY-MM.jsonld`** (where `$YYYY-MM` is an
+      `xsd:gYearMonth`):
+    Serve the file at `/$YYYY-MM/index.jsonld`.
+
+ +  **`GET /topics.jsonld`**:
+    Serve the file at `/topics/index.jsonld`.
+
+ +  **`GET /topics/$TOPIC.jsonld`** (where `$TOPIC` matches
+      `[0-9A-Za-z_-]+`):
+    Serve the file at `/topics/$TOPIC/index.jsonld`.
+
+### Atom responses
+
+These responses **should** be served with a `Content-Type` of
+  `application/atom+xml`.
+In all cases, for `/$PATH.atom`, this just serves the file at
+  `/$PATH/index.atom`.
+
+ +  **`GET /statuses.atom`**:
+    Serve the file at `/statuses/index.atom`.
+
+ +  **`GET /statuses/$YYYY-MM.atom`** (where `$YYYY-MM` is an
+      `xsd:gYearMonth`):
+    Serve the file at `/$YYYY-MM/index.atom`.
+
+ +  **`GET /topics/$TOPIC.atom`** (where `$TOPIC` matches
+      `[0-9A-Za-z_-]+`):
+    Serve the file at `/topics/$TOPIC/index.atom`.
+
+### Other Headers
+
+All responses **should** have a `Access-Control-Allow-Origin` header
+  with a value of `*` (assuming your server does not use credentials
+  and is not being served behind a firewall).
+
+## Committing Statuses To Git
+
+The `post-receive` script will run whenever you make a commit to the
+  `live` branch, which should be set as your default.
+Statuses are represented by a small collection of files committed to
+  particular locations in this repository :—
+
+ +  Files committed to `/YYYY/MM/DD/HH.MM.SSZ/` (the final component
+      can actually take any form but a time is **recommended**) are
+      ordinary statuses.
+
+ +  Files committed to `/topic/TOPICNAME/a/b/c/d/xxxx` (where `a`, `b`,
+      `c`, and `d` are lowercase hexadecimal digits and `xxxx` can be
+      anything) is a status posted to a specific topic (`TOPICNAME`).
+    It is **recommended** that you make `a/b/c/d` the first four digits
+      of an MD5 hash of the status content and `xxxx` the remaining
+      digits (security is not an issue here, so MD5 is fine).
+    `TOPICNAME` should have the form `[0-9A-Za-z_-]+`.
+
+The intent is that “ordinary statuses” are a bit more ephemeral whereas
+  “topic statuses” can serve as reference material.
+Using an MD5 hash for topic statuses ensures you don’t post the same
+  thing twice.
+
+The files which represent a status are as follows :—
+
+ +  **`text`**:
+    The text of the status.
+    Blank lines separate paragraphs; linebreaks will be preserved.
+    There is a special markup for links: `<https://link.example>`, or
+      `<https://link.example>="link text"` if you want to supply link
+      text.
+    At present, no other markup is supported.
+
+ +  **`0=x_status_git_1.0`**:
+    This file is **optional** and not currently used for anything, but
+      indicates that the post follows the `1.0` format.
+    The contents of this file, if present, **must** be
+      `x_status_git_1.0`, optionally followed by a trailing newline.
+
+ +  **`1=NAME`** (where `NAME` might be anything):
+    This file is **recommended** and indicates the author of the
+      status.
+    Only one author is currently supported.
+    The value of `NAME` **must** give the name of the author of the
+      status.
+    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.
+    The value of `YYYY-MM-DD` **should** give the date of the status,
+      although this is not used (in favour of the full timestamp).
+    The contents of this file **must** give the full `xsd:dateTime`
+      timestamp of the status, optionally followed by a trailing
+      newline.
+
+ +  **`4=IDENTIFIER`** (where `IDENTIFIER` might be anything):
+    This file is **required** and provides an identifier for the
+      status.
+    Only one identifier is currently supported.
+    The contents of this file **must** be an I·R·I which uniquely
+      identifies the status (for example, a U·U·I·D or `tag:` URI).
+    The value of `IDENTIFIER` **must** be a locally‐unique identifier
+      for the status and **should** resemble the contents where
+      possible.
+    (Note, however, that `IDENTIFIER` cannot contain slashes and need
+      not be a valid I·R·I.)
+
+Files with names that begin with the strings `2=` or `x_status_git_`
+  are reserved for backwards‐compatible extensions.
+
+x_status_git has no opinion on how these files make their way into the
+  Git repository, except that all the files for a single status should
+  be added in the same commit.
+The intention is that the simple nature of these files will make them
+  easy to automate.
+
+## I Am Computer, How Do I Get Status?
+
+Assume you are given a U·R·L `resource_url` which you think points to
+  some kind of x_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 :—
+
+    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.
+
+    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.
+
+    03. Otherwise, let `document` be null.
+
+05. If `document` is not null :—
+
+    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`.
+
+ +  **`creator`** [`dcterms:creator`] (optional):
+    The author of the status, as an object with an `@id` and `name`
+      [`foaf:name`].
+
+ +  **`identifier`** [`dcterms:identifier`]:
+    An I·R·I which uniquely identifies the status.
+    This differs from the `@id` in that it is not expected to be
+      dereferenceable.
+
+ +  **`subject`** [`dcterms:subject`] (optional):
+    The topic of the status, for topic statuses.
+
+ +  **`title`** [`dcterms:title`] (optional):
+    The title of the status.
+
+ +  **`content`** [`sioc:content`]:
+    The content of the status, as an `rdf:XMLLiteral`.
