Tracker

Tracker is a tool designed to extract information and metadata about your personal data so that it can be searched easily and quickly. It can trawl through your hard drive and index existing files and data stores.

It consists of a common object database that allows entities to have an almost infinte number of properties, metadata (both embedded / harvested as well as user definable), a comprehensive database of keywords/tags and links to other entities.

It provides additional features for file based objects including context linking and audit trails for a file object.

The software has the ability to index, store, harvest metadata, retrieve and search all types of files and other first class objects. Tracker detects file mime types and further enables you to limit searchs to specific types of files (audio, video, text files, etc.).

It is designed and built to run well on lower-memory systems with typically 128MB or 256MB memory. Typical RAM usage is between 4-30 MB.
