[NLP2RDF] Guidelines for RESTful NIF-based services

[Sebastian Hellmann]

Hi Philipp,
sorry, I should have taken a look earlier. I about to go on holiday in 
two days and as you might know the pre-holiday time is quite work 
intensive...

Yes, the guidelines look very good. I am happy that you could extract 
this from documentation.

Ciro deployed stanford and opennlp the other day and gets things 
runnging again:
http://demo.nlp2rdf.org:9999/stanfordcorenlpn?f=text&i=This+is+a+test.&t=direct

There are some minor changes, which need to be discussed.

for begin and endIndex:
Serializer should use xsd:int , Parser must accept xsd:int, xsd:long and 
xsd:nonNegativeInteger and no datatype
Note: xsd:int (32-bit signed int) is optimized by most databases and 
therefore provides benefits for SPARQL out of the box.
xsd:nonNegativeInteger is the correct datatype allowing the right-open 
interval of [0,inf) but I am not sure, if this datatype is implemented.


for anchorOf and isString:
Serializer must use xsd:string
-> this is to avoid people adding nametags, which can be ambiguous.

Other than that very good.
There is a second way to chain parsers via:
curl http://service1 -d t="url"   --dataurlencode 
"http://demo.nlp2rdf.org:9999/stanfordcorenlpn?f=text&i=This+is+a+test.&t=direct"

All the best,
Sebastian
