The "LDPImplementationReport/2014-03-11" page has been changed by JakobFrank: https://wiki.apache.org/marmotta/LDPImplementationReport/2014-03-11?action=diff&rev1=6&rev2=7 Comment: Added general restrictions = LDP Implementation Report (2014-03-11) = Implementation Report based on the [[http://www.w3.org/TR/2014/WD-ldp-20140311/|WD-ldp-20140311]]. + + == General Implementation Restrictions == + + * '''Identifiers''' + * trailing slash is ignored (removed) for URI generation. + thus http://example.com/foo and http://example.com/foo/ are treated as identic. + * 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) + * '''Storage''' + * internally every LDPR will be stored in its own (Sesame) context (as could be interpreted from [[https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#h5_ldpc-post-createrdf|sec 5.2.3.4]]) + * 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: [[http://www.w3.org/2013/meeting/ldp/2014-02-17#resolution_5|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. + * We will provide support to the full LDP hierarchy ([[http://mail-archives.apache.org/mod_mbox/marmotta-dev/201402.mbox/%3C52FA14DD.6090506%40salzburgresearch.at%3E|discussion on the mailing-list]]). + * Our interpretation of Sec. 5.2.3.12 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) + * Sec. 5.2.3.12 ('''{{{rel='describedby'}}}-Link''') will be fulfilled by pointing to this page. + {{{Link: <http://wiki.apache.org/marmotta/LDPImplementationReport>; rel="describedby"}}} + * Creating new resources using {{{HTTP PUT}}} is not allowed (Sec. 4.2.4, Sec. 5.2.4) + * For the time beeing, '''only LDP-BCs are supported''' + * '''PATCH''' accepts [[http://afs.github.io/rdf-patch/|application/rdf-patch]] only + Patches with the predicate {{{ldp:contains}}} will result in a {{{HTTP 409 Conflict}}} == 4 LDPR ==
