Marmotta LDP Implementation Report
LDP Test Cases (not updated yet with the latest changes)
Implementation Report Revisions
We agree on some restrictions:
- trailing slash is ignored (removed) for URI generation.
- query part of an URL will never be used as part of a URI.
- query parameters might be used for some LDP operations such as non-membership triples (tbd)
- resources with fragments can't be addressed directly, but can be accessed via their container (URL without fragment)
internally every LDPR will be stored in its own (Sesame) context (as could be interpreted from sec 22.214.171.124)
- that would allow us to extend the Resource concept beyond the common understanding in triplestores (just one level of outgoing triples)
Paging and Sorting is not supported
Anyway the WG has resolved (Feb 17, 2014) to move out paging and ordering into a separate spec: 2014-02-17#r5
ETags for LDP-RS are weak and soley based on the dcterms:modified value, while ETags for LDP-NR are based on the md5sum of the file content.
Both LDP-NR and LDP-NR are supported
Our interpretation of Sec. 126.96.36.199 implements that POST of content types not managed by the platform (i.e., not suitable Rio parser registered) adds a LDP-RS as member of the container, linking (dct:hasFormat/dct:isFormatOf) to the actual LDP-NR (URI is build by appending the file extension according the content type)
Only LDP-BC is supported, since current use cases do not justify the inclusion of LDP-DC or LDP-IC
Sec. 188.8.131.52 (rel='ldp:constrainedBy'-Link) is fulfilled by pointing to this page.

PATCH accepts application/rdf-patch only (LD Patch support will be discussed)
Patches with the predicate ldp:contains will result in a HTTP 409 Conflict

For accessing this experimental feature you'd need to follow these instructions:
First install all artifacts:
And launch the webapp (at launchers/marmotta-webapp/ ) with the experimental features enabled:
mvn clean tomcat7:run -Pexperimental,kiwi,cleanall
Although not strictly required, it would be good to have some background what's happening under the hood with these commands. For that, please refer to the relevant documents listed above.
Add a source resource to a container
curl -i -X POST -d @src/test/resources/test.ttl -H "Content-Type: text/turtle" -H "Slug: test" http://localhost:8080/ldp/container1 curl -i -H "Accept: text/turtle" http://localhost:8080/ldp/container1/test
Add a binary resource to a container
curl -i -X POST --data-binary @src/test/resources/test.png -H "Content-Type: image/png" -H "Slug: test2" http://localhost:8080/ldp/container2 curl -i http://localhost:8080/ldp/container2/test2 curl -i -H "Accept: text/turtle" http://localhost:8080/ldp/container2/test2.png curl -i -H "Accept: image/png" http://localhost:8080/ldp/container2/test2.png
