JabRef allows to share both Bib(La)TeX database and SQL database.
When sharing a Bib(La)TeX database, JabRef automatically recognizes a change in the
bib file on disk and notifies the user of it.
This works well on network drives.
Note: the use of a version control system (SVN, git, etc.) is recommended as this will allow for reverting changes.
To make the sharing of a Bib(La)TeX database easier, it is recommended to set specific database properties. In the menu File -> database properties:
General file directory, which will be used to store shared PDF (and other) files.
Refuse to save the database before external changes have been reviewed.
Enable save actions, and defines these actions, to help enforcing a consistent format for the entries.
