Apache Marmotta is a linked data platform that comprises several components. In its most basic configuration it is a Linked Data server.[1][2] Marmotta is one of the reference projects early implementing the new Linked Data Platform[3][4][5] recommendation that is being developed by W3C.
It has been contributed by Salzburg Research from the Linked Media Framework,[6][7][8][9] and continues its versioning, hence starting at version 3.0.0.
In November 2020, it was retired to the Apache Attic, meaning that the project is no longer being developed.[11]
Componentsedit
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:
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 (data providers) that wrap other data sources (such as YouTube and Facebook).[12]
LDCache, a cache system that automatically retrieves resources by internally using LDClient.
Historyedit
Linked Media Framework (pre-Apache)edit
Apache Marmotta is the continuation of the open source Linked Media Framework published in early 2012.[13][14]
Apache Marmottaedit
On November 16, 2012 it is proposed to the Apache Software Foundation under the name of Apache Linda, later changed to Apache Marmotta in order to avoid confusion with the Linda language.[15]
On 3 December 2012 Marmotta enters incubation.[16]
On April 26, 2013 Marmotta 3.0.0-incubating is released.[17]
On October 3, 2013 Marmotta 3.1.0-incubating is released.[18]
