vyasa
Summary
vyasa is a digital library application that incorporates the functions of digital asset and document management systems. Its primary purpose is to facilitate information retrieval and knowledge discovery by providing comprehensive metadata generation, ontological reasoning and semantic analysis.
vyasa leverages the features of a variety of asset management functions to create a comprehensive digital library solution. The strength of the project lies in the implementation and cohesion between its individual parts. These parts work together to create a flexible knowledge discovery tool that reveals the latent knowledge contained in a collection of digital assets.
Requirements
vyasa is currently in the planning and alpha stages of development. The following features have been identified by requirements analysis:
- digital asset content and format storage
- ontological and semantic analysis
- automatic metadata generation and storage
- full-text search and indexing
