TAG Roadmap for 2008 - Job vacancy!
Dear TAG Member,
With kind support from others I have now pulled together what I believe is the text for the 2008 Roadmap. I will polish this some more but do not plan to change it radically. This will be presented to the conference in Fremantle next month as the output of the TAG.
http://wiki.tdwg.org/twiki/bin/view/TAG/RoadMap2008
Please take a few moments to read this through and edit or comment on the list if you don't agree with it or think anything is missing. I will take silence as assent!
On or around the 8th October I will convert the wiki page into a PDF and start distributing it.
I would like to take this opportunity to announce that I wish to stand down as convener of the TAG as of the Fremantle conference. I believe it would be good for the TAG and TDWG to have some fresh blood in this position. I still hope to continue contributing to TDWG but perhaps in different ways.
The procedure for choosing a new convener is somewhat vague but I believe it should be done through group consensus. Perhaps we could start a discussion on this list and those who are coming to Fremantle could discuss it further.
Who do you think should take this forward? Would you like to take this forward?
All the best,
Roger

Just a thought...
REST based services seem to be gaining a lot of momentum lately, so I wonder if we should mention them in the RoadMap ?? I would at least like to bring up the subject at some point during the TDWG meeting, and look at how REST may fit in with LSIDs, etc.

Yes, I agree
REST seems a lot easier to implement, and at least having some information on how REST fits in would be helpful.
Cheers, Ben

Yes I think you are right a REST section would be good but.... What is REST? In a way the TAPIR specification (especially in its lighter versions) is 'just' a common REST specification. You pass it parameters over HTTP and you get back data as XML. On the other hand TAPIR seems more complex than just putting a REST service together. Perhaps because doing anything that meets a specification rather than just what comes to hand is going to be harder. Perhaps Renato may have comments on this.
I have actually just done a REST/JSON service for BCI.
I am nervous because it is totally not TDWG standards compliant and just a useful thing for getting data back for mashups and embedding. Effectively exposing the database to client side applications. From an engineering point of view it is dead simple - a single PHP file (within the Zend Framework). To write code to consume this is trivial (there is an example) but it is bespoke. a major thing is that the return type is JSON which I think many people think of a standard data format for REST type services.
So it would be a good to get some clarification on what we mean by REST.
Does REST tend to imply a particular return type?
If we mean REST/JSON does anyone have an idea how we could get some data typing in a JSON object so that a consuming application could tell that it is a representation of a DwC object or something from the TDWG ontology? Service description is also an issue. We end up re- inventing TAPIR if we aren't careful.
I am sure it would be trivial to wrap a TAPIR provider in something that converted the XML output to JSON enabling it to act as a data source for client mashups.
As usual I'd be grateful for opinions on this. Perhaps we should talk in Fremantle.
All the best,
Roger

Good question. It's also not easy for me to draw a line between RESTful and RESTless services.
Although TAPIR is based on operations, which could be seen as something closer to an RPC approach, it has just a few quite generic operations. On the other hand, for sure TAPIR offers simple ways to interact with the service and to easily expose URLs for any underlying resource (using the term "resource" here in the general sense). REST junkies can even configure re-write rules very easily on a web server to allow "cleaner" URLs for resources that are exposed through a TAPIR service.
I don't think TAPIR is harder just because you need to follow a specification - this could actually make things easier, obviously depending on the complexity of the specification. Remember that TAPIR was created to be used by distributed data providers who want to share the same kind of data using the same protocol, so there's all that additional stuff related with data abstraction, conceptual schemas, etc. The BCI service seems to be built on top of a central database in a single data provider scenario (or am I wrong?) so it's understandable not to use TAPIR.
I think it was Wouter who found some time ago a generic XSLT to convert any XML to JSON. I never used it and I'm not sure if I still have a copy somewhere. A first step towards standardizing JSON representations for our objects could be to play with this kind of generic stylesheet to convert TDWG ontolgy objects represented in RDF/XML to JSON.

There seem to be several mechanisms around to serialize RDF in JSON, e.g. http://n2.talis.com/wiki/RDF_JSON_Specification and http://www.gbv.de/wikis/cls/RDF_in_JSON
which may actually produce the same JSON
Also, see http://www.w3.org/TR/rdf-sparql-json-res/

Perhaps I missed this, but what is the requirement driving serialization of RDF or XML in JSON? Adoption of REST strategies does not require or even imply JSON encoding, so is the goal to provide rich content to browsers that is easily parsed by javascript applications?
In any case with the variety of formats and tools available for serializing RDF it is trivial (assuming that the XML, RDF/XML, or whatever is being produced on the fly) to support agent-driven content negotiation and have the web server respond with appropriately serialized content based on the mime type indicated in the HTTP Accept header forwarded by the client (json = application/json, rdfxml = application/rdf+xml). I guess one could also request text/csv if semantics weren't of interest.
