hopefully closes all ldap contextes
First attempt to introduce caching
- optimizes resource/:pid/all and resource/:pid/parts
- cache can be initialized using indexAll
- the cache is updated in parallel to the internal index
- a modification of a resource results now in a recursive update of
all parent nodes
- reading is optimized - modification is slower
adds some javadoc licenses etc
change the json and rdf format
- remove oai-ore statements
- introduce a self-crafted json format
- please run indexAll and switch to new index
Merge branch '0.6.0-SNAPSHOT' into unify_domainmodel
Indexing related
- modify mapping so that @context will not be touched, indexed, etc.
- remove method for chaching json
- switch on, some search tests
- update some test resources
changes embedded context document
- contentType is not a @id
- accessScheme is not a @id
- publishScheme is not a @id
- isPartOf is a @id
introduces  skos:prefLable to add display info for lod resources
- lod resources are introduced as nested objects
- for known creator, contributor and subject
- e.g.
  "subject": [
    {
        "prefLabel": "Soziale Probleme und Sozialdienste; Verbände",
        "@id": "http://dewey.info/class/360/"
    },
    {
        "prefLabel": "Freizeitgestaltung, darstellende Künste, Sport",
        "@id": "http://dewey.info/class/790/"
    }

],
add .regal endpoint (deprecated)
- is deprecated cause covered by .json
new index mapping, based on dynamic_templates
clean up imports
remove debug line
search own metadata for labels
