Catacomb is a WebDAV repository module for use with the Apache WebDAV module, mod_dav. Apache mod_dav parses WebDAV and DeltaV protocol requests into operations on a repository providing persistent storage of resources and their properties. The default repository for mod_dav is provided by a separate module, mod_dav_fs, which stores resource bodies as files in the filesystem, and stores properties in a (G)DBM database. It could be used for server side searching and versioning of files over the HTTP protocol.
Fuseki is a server that provides access to the SPARQL 1.1 standard. SPARQL is a W3C query language for RDF data on the Semantic Web. It forms a part of the Jena semantic web project. Fuseki provides the REST-style SPARQL HTTP Update, and SPARQL Query and SPARQL Update using the SPARQL protocol over HTTP. The SPARQL standards are works-in-progress by the SPARQL working group and while the general designs are stable, details may change. Fuseki will track the draft standards.
Geo Bookmark is a simple widget that adds a bookmark with the current time and geographical position to the home screen. The interface is kept minimal to allow operation in situations that do not permit extensive interaction with the phone (e.g. while driving a car). Bookmarks are color coded. Blue icons represent exact locations, red icons mean that the widget could not get a GPS fix within 40 seconds and therefore recorded the last known location (which may or may not have been determined by means other than GPS). In order to view a bookmark, a suitable maps application needs to be installed (e.g. Google Maps or OSMAnd).
The Generic Repository (grepo) is a framework for Java which allows you to access (database) repositories in a generic and consistent manner. Using grepo, it is generally no longer required to provide all the boilerplate code which is necessary in order to access (database) repositories from Java. All you have to do is write appropriate database code (queries, procedures, functions, etc.), an appropriately annotated Java interface, and very little Spring configuration.
The Privilege Separation patches for Apache HTTPD and 'mod_dav' address the problem that an Apache WebDAV server can only write files as the non-privileged Web server user (usually something like 'nobody' or 'www'). The patches address this shortcoming in a secure way by adding privilege separation to the Apache Web server (conceptually similar to SSH privilege separation). A privilege-separated Apache can be used to provide secure WebDAV write access to ~user directories and allow the use of per-user Unix quotas. When combined with mod_ssl, it provides a convenient and secure remote file serving system, as WebDAV clients are seamlessly integrated into both Windows and Mac OS X.
