Description

Marmotta is defining a service for all operations required by LDP:

https://git-wip-us.apache.org/repos/asf?p=marmotta.git;a=blob;f=platform/marmotta-ldp/src/main/java/org/apache/marmotta/platform/ldp/api/LdpService.java;h=9a746da1929c132be240cce6a4ee57ca871bca68;hb=refs/heads/ldp

The default implementation uses the native Sesame API:

https://git-wip-us.apache.org/repos/asf?p=marmotta.git;a=blob;f=platform/marmotta-ldp/src/main/java/org/apache/marmotta/platform/ldp/services/LdpServiceImpl.java;h=b49f9d25ae429a16056b1f935fe2904ac79d5b93;hb=refs/heads/ldp

The idea is to explore how feasible is to provide an alternative implementation pure based on SPARQL. Therefore, the required skill would include Java, of course, and a deep knowledge of SPARQL 1.1.
