Dr. Ben Martin and Associate Professor Martin Sevior

Abiword is an open source word processor with advanced collaboration capabilities. Documents can be shared either stored on abicollab.net or edited on a purely peer to peer basis.

Abiword has recently gained RDF support across its native abw format, RTF, as well ODF format files. RDF is the base layer of the Semantic Web and allows the meaning of information to be described in a manner that a computer can understand. The intention of RDF in abiword is not an academic one. Instead it should allow the computer to offer authors and viewers assistance based on knowledge from the document. For example, that “Fred” refers to “Fred Smith” who has a specific phone number and will be at the meeting next week. Incidentally, that this meeting is more than 2 hours drive and you might like to make arrangements to get there soon. Perhaps a specific flight in your itinerary is canceled due to some ash cloud, it would be nice to know that while reading the document.

While things are built on RDF, you should also be able to make use of it without being a convert. Dragging a location from Google Earth to abiword should import a geolocation into RDF in the document. Likewise for events and contacts in your email and groupware software. Information should move as you like rather than constrain you. The RDF portion of the talk will tell you what and how you can do things now and where things are heading with semantics and abiword.

With the port to Gtk+-3, abiword can now have it’s interface shown in a Web browser. Together with abicollab for storage this allows abiword to run both storage and processing in the cloud. No longer are users subjected to the limited editing capabilities of wikis; pages can be edited with abiword presented through HTML and viewed as HTML,PDF, ODF, or ebook files.

In 2011 abiword was one of the first word processors to support the proposed Generic Change Tracking (GCT) proposal from the OASIS group. The GCT includes constructs to markup XML so that the changes, additions, deletions of elements can be tracked as well as their coalescing. Attributes such as the text style, colour etc are traced using an attribute stack in the XML. Change Tracking in ODF allows governments and businesses to see the evolution of a document, sign off on changes and provide audit trails, and because all this happens in a truely open XML document standard, the ODF files can be read and written by a wide range of software.
