Any new project is intimidating and jumping right into the [http://api.kde.org/4.x-api/kdelibs-apidocs/nepomuk-core/html/index.html API Documentation] can be scary. So, we have prepared some articles which explain the different aspects of '''Nepomuk''' and even touch on some advanced features.

The documentation of any project is always in progress as the code base is always evolving. If you feel that the documentation is lacking in some regard, please come talk to us. We'd love to hear your feedback, and the documentation might just get improved in the process.

[edit] About Nepomuk

Nepomuk serves as a cross application semantic storage backend. It aims at collecting data from various sources - file indexing, the web, applications, etc, and linking them all together to form a cohesive map of data.

This page is dedicated to third party documentation for Nepomuk. To know more about Nepomuk from a user's point of view, head over to the Nepomuk page on UserBase. Or to know more about the Nepomuk community and getting involved in Nepomuk, head over to the Nepomuk Community Page.

[edit] Documentation

Any new project is intimidating and jumping right into the API Documentation can be scary. So, we have prepared some articles which explain the different aspects of Nepomuk and even touch on some advanced features.

The documentation of any project is always in progress as the code base is always evolving. If you feel that the documentation is lacking in some regard, please come talk to us. We'd love to hear your feedback, and the documentation might just get improved in the process.
