Hi Sebastian, all,<br>
<br>
one question: have you ever thought about recommending a paramter
for NIF-based services that controls the verbosity of the output.
Verbosity could take two values: full or minimal.<br>
<br>
Full would return the full NIF output containing the input document
plus the additional annotations.<br>
<br>
Minimal: would only return the additional triples added.<br>
<br>
I think this would be very useful because it allows to minimize the
data sent back by a NIF service.<br>
<br>
I am sure you have thought about this already. What is your position
with respect to this?<br>
<br>
Best regards,<br>
<br>
Philipp.<br>

<div class="moz-cite-prefix">Also, I still haven't found the time
to check in detail whether it makes sense to restrict all NIF

needs some thought and I need to read about REST once more. <br>

JSON-LD will also come soon, but some RDF parsers don't read it,
because it is too complicated to parse: <br>

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

<br>
There are some minor changes, which need to be discussed.<br>
<br>
for begin and endIndex: <br>
Serializer should use xsd:int , Parser must accept xsd:int,
xsd:long and xsd:nonNegativeInteger and no datatype<br>
Note: xsd:int (32-bit signed int) is optimized by most
databases and therefore provides benefits for SPARQL out of
the box. <br>
xsd:nonNegativeInteger is the correct datatype allowing the
right-open interval of [0,inf) but I am not sure, if this
datatype is implemented. <br>
<br>
<br>
for anchorOf and isString:<br>
Serializer must use xsd:string <br>
-> this is to avoid people adding nametags, which can be
ambiguous.<br>
<br>
Other than that very good.<br>
There is a second way to chain parsers via:<br>
curl <a moz-do-not-send="true" class="moz-txt-link-freetext"
href="http://service1">http://service1</a> -d t="url"
--dataurlencode <a moz-do-not-send="true"
class="moz-txt-link-rfc2396E"

I was wondering why I have received no feedback other than
from Mariano Rico on the document I sent two weeks ago. My
goal is to finalize the guidelines for the LIDER project this
week, so I would appreciate any feedback. Confirming that the
way we have implemented the NIF-based services is fine would
also be an important type of feedback ;-) <br>
<br>
I attach the document again for ease of reference. <br>
<br>
Any feedback is welcome, thanks a lot! <br>

I just joined the list. In the context of the European
LIDER project, I am trying to put together some guidelines
on how to implement NIF-based Restful NLP services. <br>
<br>
Our student Benjamin Siemoneit (CC) has put together a
document describing how he has set up two services, wrapping
the Stanford POS tagger and the Stanford parser. <br>
<br>
The document is attached. I would be very happy to get some
feedback on the document, i.e. on <br>
<br>
1) Parameters of services <br>
2) use of NIF vocabulary <br>
3) chaining of services via curl <br>
<br>
Enjoy the document ;-) <br>
