Granary granary Circle CI Coverage Status

The social web translator. Fetches and converts data between social networks, HTML and JSON with microformats2, ActivityStreams/ActivityPub, Atom, JSON Feed, and more.

About

Granary is a library and REST API that fetches and converts between a wide variety of social data sources and formats:

Free yourself from silo API chaff and expose the sweet social data foodstuff inside in standard formats and protocols!

Here's how to get started:

License: This project is placed in the public domain. You may also use it under the CC0 License.

Using

The library and REST API are both based on the OpenSocial Activity Streams service. Let's start with an example. This code using the library:

from granary import twitter
...
tw = twitter.Twitter(ACCESS_TOKEN_KEY, ACCESS_TOKEN_SECRET)
tw.get_activities(group_id='@friends')

is equivalent to this HTTP GET request:

https://granary.io/twitter/@me/@friends/@app/
  ?access_token_key=ACCESS_TOKEN_KEY&access_token_secret=ACCESS_TOKEN_SECRET

They return the authenticated user's Twitter stream, ie tweets from the people they follow. Here's the JSON output:

{
  "itemsPerPage": 10,
  "startIndex": 0,
  "totalResults": 12,
  "items": [{
      "verb": "post",
      "id": "tag:twitter.com,2013:374272979578150912",
      "url": "http://twitter.com/evanpro/status/374272979578150912",
      "content": "Getting stuff for barbecue tomorrow. No ribs left! Got some nice tenderloin though. (@ Metro Plus Famille Lemay) http://t.co/b2PLgiLJwP",
      "actor": {
      "username": "evanpro",
        "displayName": "Evan Prodromou",
        "description": "Prospector.",
        "url": "http://twitter.com/evanpro",
      },
      "object": {
        "tags": [{
            "url": "http://4sq.com/1cw5vf6",
            "startIndex": 113,
            "length": 22,
            "objectType": "article"
          }, "..."],
      },
    }, "..."]
  "..."
}

The request parameters are the same for both, all optional: USER_ID is a source-specific id or @me for the authenticated user. GROUP_ID may be @all, @friends (currently identical to @all), @self, @search, or @blocks; APP_ID is currently ignored; best practice is to use @app as a placeholder.

Paging is supported via the startIndex and count parameters. They're self explanatory, and described in detail in the OpenSearch spec and OpenSocial spec.

When using the GROUP_ID @search (for platforms that support it — currently Twitter and Instagram), provide a search string via the q parameter. The API is loosely based on the OpenSearch spec, the OpenSocial Core Container spec, and the OpenSocial Core Gadget spec.

Output data is JSON Activity Streams 1.0 objects wrapped in the OpenSocial envelope, which puts the activities in the top-level items field as a list and adds the itemsPerPage, totalCount, etc. fields.

Most Facebook requests and all Twitter, Instagram, and Flickr requests will need OAuth access tokens. If you're using Python on Google App Engine, oauth-dropins is an easy way to add OAuth client flows for these sites. Otherwise, here are the sites' authentication docs: Facebook, Flickr, Instagram, Twitter.

If you get an access token and pass it along, it will be used to sign and authorize the underlying requests to the sources providers. See the demos on the REST API endpoints above for examples.

Using the REST API

The endpoints above all serve the OpenSocial Activity Streams REST API. Request paths are of the form:

/USER_ID/GROUP_ID/APP_ID/ACTIVITY_ID?startIndex=...&count=...&format=FORMAT&access_token=...

All query parameters are optional. FORMAT may be as1 (the default), as2, atom, html, jsonfeed, mf2-json, rss, or xml (the default). atom supports a boolean reader query parameter for toggling rendering appropriate to feed readers, e.g. location is rendered in content when reader=true (the default). The rest of the path elements and query params are described above.

Errors are returned with the appropriate HTTP response code, e.g. 403 for Unauthorized, with details in the response body.

By default, responses are cached and reused for 10m without re-fetching the source data. (Instagram responses are cached for 60m.) You can prevent this by adding the cache=false query parameter to your request.

Include the shares=false query parameter to omit shares, eg Twitter retweets, from the results.

To use the REST API in an existing ActivityStreams/ActivityPub client, you'll need to hard-code exceptions for the domains you want to use e.g. facebook.com, and redirect HTTP requests to the corresponding endpoint above.

Facebook and Instagram are disabled in the REST API entirely, sadly.

Using the library

See the example above for a quick start guide.

Clone or download this repo into a directory named granary. Each source works the same way. Import the module for the source you want to use, then instantiate its class by passing the HTTP handler object. The handler should have a request attribute for the current HTTP request.

The useful methods are get_activities() and get_actor(), which returns the current authenticated user (if any). See the full reference docs for details. All return values are Python dicts of decoded ActivityStreams 1 JSON.

The microformats2.*_to_html() functions are also useful for rendering ActivityStreams 1 objects as nicely formatted HTML.

Troubleshooting/FAQ

Check out the oauth-dropins Troubleshooting/FAQ section. It's pretty comprehensive and applies to this project too.

Future work

We'd love to add more sites! Off the top of my head, YouTube, Tumblr, WordPress.com, Sina Weibo, Qzone, and RenRen would be good candidates. If you're looking to get started, implementing a new site is a good place to start. It's pretty self contained and the existing sites are good examples to follow, but it's a decent amount of work, so you'll be familiar with the whole project by the end.

Development

Pull requests are welcome! Feel free to ping me in #indieweb-dev with any questions.

First, fork and clone this repo. Then, install the Google Cloud SDK and run gcloud components install beta cloud-datastore-emulator to install the datastore emulator. Once you have them, set up your environment by running these commands in the repo root directory:

gcloud config set project granary-demo
python3 -m venv local
source local/bin/activate
pip install -r requirements.txt
# needed to serve static files locally
ln -s local/lib/python3*/site-packages/oauth_dropins/static oauth_dropins_static

Now, run the tests to check that everything is set up ok:

gcloud beta emulators datastore start --use-firestore-in-datastore-mode --no-store-on-disk --host-port=localhost:8089 --quiet < /dev/null >& /dev/null &
python3 -m unittest discover

Finally, run the web app locally with flask run:

GAE_ENV=localdev FLASK_ENV=development flask run -p 8080

Open localhost:8080 and you should see the granary home page!

If you want to work on oauth-dropins at the same time, install it in editable mode with pip install -e <path to oauth-dropins repo>. You'll also need to update the oauth_dropins_static symlink, which is needed for serving static file handlers locally: ln -sf <path-to-oauth-dropins-repo>/oauth_dropins/static oauth_dropins_static.

To deploy to production:

gcloud -q beta app deploy --no-cache granary-demo *.yaml

The docs are built with Sphinx, including apidoc, autodoc, and napoleon. Configuration is in docs/conf.py To build them, first install Sphinx with pip install sphinx. (You may want to do this outside your virtualenv; if so, you'll need to reconfigure it to see system packages with virtualenv --system-site-packages local.) Then, run docs/build.sh.

Release instructions

Here's how to package, test, and ship a new release. (Note that this is largely duplicated in the oauth-dropins readme too.)

  1. Run the unit tests. 
    source local/bin/activate.csh
CLOUDSDK_CORE_PROJECT=granary-demo gcloud beta emulators datastore start --use-firestore-in-datastore-mode --no-store-on-disk --host-port=localhost:8089 < /dev/null >& /dev/null &
sleep 5
python3 -m unittest discover
kill %1
deactivate
  2. Bump the version number in setup.py and docs/conf.py. git grep the old version number to make sure it only appears in the changelog. Change the current changelog entry in README.md for this new version from unreleased to the current date.
  3. Bump the oauth-dropins version specifier in setup.py to the most recent version.
  4. Build the docs. If you added any new modules, add them to the appropriate file(s) in docs/source/. Then run ./docs/build.sh. Check that the generated HTML looks fine by opening docs/_build/html/index.html and looking around.
  5. git commit -am 'release vX.Y'
  6. Upload to test.pypi.org for testing. 
    python3 setup.py clean build sdist
setenv ver X.Y
source local/bin/activate.csh
twine upload -r pypitest dist/granary-$ver.tar.gz
  7. Install from test.pypi.org. 
    cd /tmp
python3 -m venv local
source local/bin/activate.csh
pip3 uninstall granary # make sure we force Pip to use the uploaded version
pip3 install --upgrade pip
pip3 install mf2py==1.1.2
pip3 install -i https://test.pypi.org/simple --extra-index-url https://pypi.org/simple granary==$ver
deactivate
  8. Smoke test that the code trivially loads and runs. 
    source local/bin/activate.csh
python3
# run test code below
deactivate
    Test code to paste into the interpreter: 
    import json
from granary import github
github.__file__  # check that it's in the virtualenv

g = github.GitHub('XXX')  # insert a GitHub personal OAuth access token
a = g.get_activities()
print(json.dumps(a, indent=2))

from granary import atom
print(atom.activities_to_atom(a, {}))
  9. Tag the release in git. In the tag message editor, delete the generated comments at bottom, leave the first line blank (to omit the release "title" in github), put ### Notable changes on the second line, then copy and paste this version's changelog contents below it. 
    git tag -a v$ver --cleanup=verbatim
git push && git push --tags
  10. Click here to draft a new release on GitHub. Enter vX.Y in the Tag version box. Leave Release title empty. Copy ### Notable changes and the changelog contents into the description text box.
  11. Upload to pypi.org! 
    twine upload dist/granary-$ver.tar.gz
  12. Build the docs on Read the Docs: first choose latest in the drop-down, then click Build Version.
  13. On the Versions page, check that the new version is active, If it's not, activate it in the Activate a Version section.

Related work

Apache Streams is a similar project that translates between storage systems and database as well as social schemas. It's a Java library, and its design is heavily structured. Here's the list of formats it supports. It's mainly used by People Pattern.

Gnip similarly converts social network data to ActivityStreams and supports many more source networks. Unfortunately, it's commercial, there's no free trial or self-serve signup, and plans start at $500.

DataSift looks like broadly the same thing, except they offer self-serve, pay as you go billing, and they use their own proprietary output format instead of ActivityStreams. They're also aimed more at data mining as opposed to individual user access.

Cliqset's FeedProxy used to do this kind of format translation, but unfortunately it and Cliqset died.

Facebook used to officially support ActivityStreams, but that's also dead.

There are a number of products that download your social network data, normalize it, and let you query and visualize it. SocialSafe is one, although the SSL certificate is currently out of date. ThinkUp was an open source product, but shuttered on 18 July 2016. There's also the lifelogging/lifestream aggregator vein of projects that pull data from multiple source sites. Storytlr is a good example. It doesn't include Facebook, or Instagram, but does include a number of smaller source sites. There are lots of others, e.g. the Lifestream WordPress plugin. Unfortunately, these are generally aimed at end users, not developers, and don't usually expose libraries or REST APIs.

On the open source side, there are many related projects. php-mf2-shim adds microformats2 to Facebook and Twitter's raw HTML. sockethub is a similar "polyglot" approach, but more focused on writing than reading.

5.0 - 2022-12-03

Breaking changes:

  • Drop Python 3.6 support. Python 3.7 is now the minimum required version.
  • Twitter, Instagram, Mastodon:
    • Drop get_activities cache kwarg's support for App Engine memcache interface. It's now only used as a plain dict. get_activities will now make many small modifications, so if you pass an object that implements those as API calls, you'll probably want to batch those separately.
  • Twitter, Mastodon, Flickr, GitHub:
    • create/preview: support the AS1 favorite verb as well as like. (bridgy#1345)
  • Atom:
    • Switch to converting AS1 id (instead of url) to Atom id.
  • Reddit:
    • Implement get_actor.
  • Mastodon:
    • create/preview: allow non-Mastodon replies, ie activities that include inReplyTo URLs even if none of them point to a toot. (bridgy#1321)
    • Raise requests.HTTPError with response.status_code 502 instead of JSONDecodeError on non-JSON responses. This is synthetic, but more helpful for error handling.
  • microformats2:
    • object_to_json and related functions: handle all escaped HTML entities, not just &amp; &lt; &gt;.
    • Unify microformats2.prefix_image_urls and prefix_video_urls into a new as1.prefix_urls function.
  • RSS:
  • ActivityStreams 2:
    • Translate both url and urls from AS1 into multi-valued AS2 url field.
  • Move a number of utility methods from the Source class to a new as1 module: object_type, merge_by_id, is_public, add_rsvps_to_event, get_rsvps_from_event, activity_changed, append_in_reply_to, actor_name, original_post_discovery.
  • as1.original_post_discovery: remove deprecated cache kwarg.

Non-breaking changes:

  • ActivityStreams 2:
    • Fix spec compliance bug: icon and image are singly valued, not multiply valued.
    • Add new is_public method and PUBLIC_AUDIENCE constant.
    • Prefer "objectType": "featured" first in the image field when converting from AS1, last in the icon field. This matches the ActivityPub (Mastodon) convention of using icon for profile pictures and image for header images.
    • Propagate url values into new PropertyValue attachments on Person objects; these end up in Mastodon's "profile metadata" link fields.
    • to_as1: if an attachment's mediaType is image/..., override objectType and set it to image.
  • Twitter
    • Trim alt text in line between post preview and creation
    • Correctly trim Twitter alt text
  • Facebook
    • Scraping: extract post id and owner id from data-ft attribute and _ft_ query param more often instead of story_fbid, which is now an opaque token that changes regularly. (facebook-atom#27)
  • Instagram
    • Add new Instagram.scraped_json_to_activities method.
  • GitHub
    • create and preview: convert profile URLs to @-mentions, eg https://github.com/snarfed to @snarfed (bridgy#1090).
      • get_activities with activity_id now supports fetch_replies and fetch_likes.
  • Reddit
    • Add cache support to get_activities.
  • REST API
    • Add new /scraped endpoint that accepts POST requests with silo HTML as input. Currently only supports Instagram. Requires site=instagram, output=... (any supported output format), and HTML as either raw request body or MIME multipart encoded file in the input parameter.
  • microformats2
    • Add new extra and body_class kwargs to activities_to_html.
    • When converting u-featured images to AS1, add new non-standard "objectType": "featured" field to distinguish them from u-photo.
    • Convert p-note to AS1 summary.
    • Bug fixes for converting image attachments to photo.
  • Source.original_post_discovery: add new max_redirect_fetches keyword arg.

4.0 - 2022-03-23

Breaking changes:

  • Drop Python 3.5 support. Python 3.6 is now the minimum required version.

Non-breaking changes:

  • RSS:
    • Add support for RSS input via new rss.to_activities function.
  • Add new include_shares kwarg to get_activities, implemented for Twitter and Mastodon. Defaults to True. If False, shares (retweets in Twitter, boosts in Mastodon) will be discarded and not returned. Also add a corresponding shares query param to the REST API.
  • Instagram (scraping):
    • Handle media items with no user object, add new fetch for comments.
    • Add Instagram.merge_scraped_comments().
  • ActivityStreams 2:
    • Handle error when type isn't a string.
  • Reddit:
    • Implement get_activities() to fetch posts by the current user or a user specified with user_id.
  • Facebook scraping:
    • Skip "Suggested for you" posts.
    • Add log_html kwarg to get_activities; defaults to False.
    • Miscellaneous bug fixes.
  • JSONFeed:
    • Handle malformed items.author element.

3.2 - 2021-09-15

  • Source.original_post_discovery: add new include_reserved_hosts kwarg, defaults to True.
  • Instagram:
    • Update scraping to handle new feed_v2 JSON format.
  • Facebook:
    • Scraping: handle pictures, videos, link attachments, and text links in timeline/news feed posts.
  • Mastodon:
    • Bug fix for get_activities() with fetch_mentions=True: handle notifications with status: null. Maybe happens when a status is deleted?
    • create/preview_create: support bookmarks. (Nothing special happens with them; their content is posted as a normal toot.)
  • microformats2:
    • Stop rendering image.displayName as visible text in HTML, since it's already in the <img>'s alt attribute.
    • Add bookmark-of support.
    • Add prefix_image_urls() function.
    • Handle null content in AS1/2 objects.
    • json_to_object bug fix for composite bookmark-of properties.
  • Twitter:

    • Publish: preserve <code> tags instead of converting them to `s so that GitHub renders HTML entities like &gt; inside them instead of leaving them escaped. Background.
  • JSON Feed:
    • Handle malformed attachments better.

    • Don't crash on string context fields.
    • html_to_activities(): limit to h-entry, h-event, and h-cite items (#192).

  • Add Mastodon support!
  • Add Python 3.7 support, and improve overall Python 3 compatibility.
  • Update a number of dependencies.
  • Switch from Python's built in json module to ujson to speed up JSON parsing and encoding.
  • Add duration and size support to ActivityStreams 1 and 2, RSS, and microformats2 HTML and JSON. microformats2 support is still emerging for both. Both integer seconds and ISO 8601 string durations are supported for duration. Integer bytes is used for size everywhere. microformats2 HTML also includes human-readable strings, eg 5.1 MB. (#169)

2.1 - 2019-09-04

  • Convert AS2 Mention tags to AS1 objectType mention (non-standard) and vice versa (snarfed/bridgy-fed#46).

  • RSS:
    • Default title to ellipsized content.

    • Encode &s in author URL and email address too. (Thanks sebsued!)
  • AS2:
    • Add Follow support.

  • Twitter:
    • Support ISO 8601 formatted created_at timestamps, which the archive download uses, as well as RFC 2822 from the API.
    • create() and preview_create(): support RSVPs. Tweet them as normal tweets with the RSVP content. (snarfed/bridgy#818)
    • create() and preview_create(): support alt text for images, via AS1 displayName. (snarfed/bridgy#756).
  • Instagram:
    • Add global rate limiting lock for scraping. If a scraping HTTP request gets a 429 or 503 response, we refuse to make more requests for 5m, and instead short circuit and return the same error. This can be overridden with a new ignore_rate_limit kwarg to get_activities().
  • GitHub:
    • Add tag support to create/preview_create to add label(s) to existing issues (snarfed/bridgy#811).

  • Instagram:
    • Fix scraping profile pages.
  • Twitter:
    • Update character counting to handle Twitter change that now auto-links all ccTLDs. Background.
  • GitHub:
    • Bug fix for get_activities() with deleted issues and repos.
  • microformats2:
    • object_to_json(): convert tags to simple strings in the category property, not full nested objects like h-cards (#141).
    • Special case GitHub issues that are in-reply-to a repo or its /issues URL to be objectType issue.
    • Render simple string categories in HTML output.

This release is intentionally small and limited in scope to contain any impact of the Python 3 migration. It should be a noop for existing Python 2 users, and we've tested thoroughly, but I'm sure there are still bugs. Please file issues if you notice anything broken!

1.11 - 2018-03-09

  • Add GitHub!
    • get_activities() supports issues and pull requests, including comments and reactions. It's currently based on notifications, so it's best effort, not comprehensive, and only includes recently active issues/PRs.

    • Extract more user (author) data from scraped profile pages.
    • Fix home page feed scraping.
  • microformats2, Atom:

  • Atom:
    • Fix timezone bugs in updated and published.
  • JSON Feed:
    • Omit title from items if it's the same as the content. (Often caused by microformats2's implied p-name logic.)

  • Google+:
    • Update HTML scraping to handle changed serialized JSON data format.
  • Atom:
    • Add new activity_to_atom() function that renders a single top-level <entry> instead of <feed>.
    • Add new reader query param for toggling rendering decisions that are specific to feed readers. Right now, just affects location: it's rendered in the content when reader=true (the default), omitted when reader=false.
    • Include author name when rendering attached articles and notes (e.g. quote tweets).
    • Only include AS activity:object-type and activity:verb elements when they have values.

  • Source.get_activities(): start raising ValueError on bad argument values, notably invalid Facebook and Twitter ids and Instagram search queries.
  • Fix rendering and linkifying content with Unicode high code points (ie above the 16-bit Basic Multilingual Plane), including some emoji, on "narrow" builds of Python 2 with --enable-unicode=ucs2, which is the default on Mac OS X, Windows, and older *nix.

1.6 - 2016-11-26

  • Twitter:
    • Handle new "extended" tweets with hidden reply-to @-mentions and trailing URLs for media, quote tweets, etc. Background: https://dev.twitter.com/overview/api/upcoming-changes-to-tweets

    • Better username detection. Flickr's API is very inconsistent about username vs real name vs path alias. This specifically detects when a user name is probably actually a real name because it has a space.
    • Uploading: detect and handle App Engine's 10MB HTTP request limit.
    • Bug fix in create: handle unicode characters in photo/video description, hashtags, and comment text.
  • Atom:
    • Bug fix: escape &s in attachments' text (e.g. quote tweets).
