The LinDA project aims to provide tools for small and medium enterprises to access and analyze public sector information. The project will develop a transformation engine to convert data into semantic formats, a repository for linked data vocabularies, a linked data API, visualization tools, and analytics applications. These tools will help SMEs integrate public and private data sources to discover new patterns and develop innovative business models. The goal is to motivate more publication and use of open government data using semantic web standards.

Motivation
Public organizations are making available more and more
valuable data
Existing public data, however, is in most cases published in an
unstructured format not suitable for direct machine processing
In addition, the use of standards such as RDF allowing true
semantic enrichment of dataset is not widespread
Therefore, effort and costs for accessing, linking and exploiting
these data is unaffordable for SMEs
LinDA aims to fill this gap by providing an unifying set of tools to
seamlessly renovating PSI and linking to SMEs own data
