Apache Marmotta


Apache Marmotta is a linked data platform that comprises several components. In its most basic configuration it is a Linked Data server. Marmotta is one of the reference projects early implementing the new Linked Data Platform recommendation that is being developed by W3C.
It has been contributed by Salzburg Research from the Linked Media Framework, and continues its versioning, hence starting at version 3.0.0.
Since April 2013, it is listed among the Semantic Web tools by the W3C.
In November 2020, it was retired to the Apache Attic, meaning that the project is no longer being developed.

Components

The project is split in several parts: the platform itself, which includes full Read Write Linked Data, SPARQL, LDP, Reasoning, and basic security. In addition to the platform, the project develops some libraries can also be used separately:
  • KiWi, a Triplestore built on top of a relational database.
  • LDPath, a path language to navigate across Linked Data resources.
  • LDClient, a Linked Data client that allows retrieval of remote resources via different protocols by making use of pluggable adapters that wrap other data sources.
  • LDCache, a cache system that automatically retrieves resources by internally using LDClient.
