Features

Gnowsis is a Semantic Web desktop System. It consists of a Local Server and a Browser. The adapters read data from different sources and make your information available as RDF. Parts of the framework can be used seperately. You will like these parts.

Server Features

• Local RDF Database (Jena Model based)
• Data integration Hub. integrates different Data sources.
• XML/RPC API
• Java Client API
• full text indexing (using Apache Lucene)
• local webserver for experiments (using Jetty)

Adapters

Adapters take information from applications and convert them to RDF. This is done only when needed, on the fly. Data remains in the applications and is only viewed as RDF. There are adaptors to access in RDF:

• Filesystem adapter
• MP3-ID3 tag adapter (using MP3 Library by Jens Vonderheide)
• Microsoft Outlook adapter
• Mozilla Thunderbird email adapter
• Mozilla Firefox bookmarks adapter

Browser Features

• Browse the local Semantic Desktop
• shows related information for any resource
• Manage your projects using ordinary File Folders
• full text search
• Link anything with drag-drop
• annotate photos and persons

Framework features

• Handy RDF utilities: org.gnowsis.util.*
• Remote Models. Access your jena Models on remote servers like they are local, through the Jena model interface and XML-RPC magic. See org.gnowsis.util.remotemodel
• File backed models with convenience. Have your model save every X seconds to a file! See org.gnowsis.util.filemodel

Non-Features

Something is too much for gnowsis.

• RDF data in Gnowsis is read only.
• Stability and performance. This is a research prototype. Don't use it in commercial projects. This is alpha. Wait a few months and it will be beta.
