Defined in terms of OpenURL ContextObjects, with some augmentation
Some documentation, not very extensively exploited (Pubget wrote it…)
Integration Plugins
Exist for WinWord, MacWord, [Open|Libre|Neo]Office
No documentation. Each one requires a Firefox plugin. But could be written for more systems
Rtfscan also exists– a means of scanning a text file and finding references to items, then turning them into citations, using a specific style. This is underdeveloped, and it could be used in conjunction with something like Gnotero to provide facility much like Papers2's Magic Manuscripts (the bulk of which is already provided by Gnoter)
Connector Server
Designed to support Standalone
Plugins for browsers send URLs, page source to Zotero
Designed to be ported to other browsers (and other programs too!)
Could be used for a central Zotero instance, with port forwarding…
Could be used to force-feed items to Zotero
But only one-way (write to DB)
Attempt to write some docs before Madison– maybe an example client that sends items to Zotero?
Sqlite
Concurrent read-only access is fine: used by Mendeley and Gnotero
Write access is asking for trouble. But connector or server API can be used to push items into Zotero; the latter can even modify existing items
Z(ot)eroConf
Defunct (?) code in the source tree
Allowed browsing of other libraries on a local network
Fulltext parsers
Dan says not to touch this yet
Due to be replaced by Libertexto, we hope
But really… could be extended now.
Provided by the server
Metadata Syncing
File syncing
Zotero File Storage
WebDAV
Server API
read item data, styled citations (and sets of citations)
write item data
with the caveat of possible latency, this is a pretty promising direction. Syncing is pretty speedy now, so reading from Sqlite and writing to the server may be possible.
N.B. Preceding three are currently open-source, but no one has really gotten things going outside of CHNM
Devs not providing support for this as a project, but encourage people to experiment. Unfortunately, docs at zitation.org seem to be gone (indeed, why were they ever hosted not on zotero.org? No one said the docs would be discouraged… just not a project that they can do tech support on)
Website
Supposed to be improving greatly very soon
Not currently open-source, don't know if it will be. But the commits are showing up in Trac now
Other stuff
A data interchange format approximately equivalent to the one currently fed to citeproc-js is on its way to standardizing (and making interoperable) citations in word processed documents, between Z and Mendeley
