- it **houses the source code for the** [**documentation**](https://islandora.github.io/documentation/) of the [**Islandora project**](https://islandora.ca/) (versions 2.x and above).
- it **houses the source code for the** [**documentation**](https://islandora.github.io/documentation/) of the [**Islandora project**](https://islandora.ca/) (versions 2.x and above).
- it **hosts the central** [**issue queue**](https://github.com/Islandora/documentation/issues) **for the entire Islandora project**. Add an issue there if you have a use case that isn't addressed, or find a bug.
- its [Wiki](https://github.com/Islandora/documentation/wiki) **contains the archived minutes** for Islandora Tech calls and User calls of previous years. **To find current meeting minutes, please navigate to our** [**community-wiki**](https://github.com/Islandora/islandora-community/wiki).

Alpaca contains several OSGI modules or bundles. They are grouped together as features and deployed to Karaf container.

## [OSGi](https://www.osgi.org/developer/architecture/)
OSGi is a specification to develop and deploy modular Java applications. It allows for dynamic deployment (hot deployment) and dependency management.
OSGi is a specification to develop and deploy modular Java applications. It allows for dynamic deployment (hot deployment) and dependency management.

The base unit of resources is called a bundle. Bundle is similar to a jar file, with additional information to be processed as an OSGi component. Several bundles can be grouped together into a Feature and installed together. OSGi bundles can be run on containers implementing the OSGi specification. Apache Karaf is one such container
