Augusto,

I am interested in learning about HAL and look forward to this discussion. 
 But I am a bit concerned with the way you phrase these sentences:

"There should be a way to at first publish open data resources that are 
linked, but without rdf, such as in xml and json. Then, at a later date, 
improve with a descriptive rdf vocabulary and expressed in rdf to become 
linked open data (preferrably, if possible, keeping compatibility with 
clients that implemented reading the previous non-semantic version)."

To me this reads that non-rdf methods like xml and json are accommodations 
to constituents who "have not yet seen the light of RDF" and I want to 
make sure we are providing best practices standards recommendations to the 
world that exists rather than the "perfect world" we would like someday to 
exist.

At IBM, we make software that runs on many operating systems.  Of course 
we employ people with preferences for OSX, Linux, Systemz, AIX, Unix, and 
even Windows.  Heck, many ATMS around the world still run on OS/2...

But because our customers run all of the above we supply them with all of 
the above solutions. 

Can we agree on an "all of the above" approach to DWBP (without suggesting 
that everything someday becomes RDF) too?

Best Regards,

Steve

Re: Data "on" the Web vs Data "in" the Web



Hi,

this is a very important point, Ig. My thoughts exactly when I suggested 
we look at the Hypertext Application Language (HAL) proposal [1] in the 
first meeting. It was in fact an invitation for us to think about data 
"in" the web, as in "part of the web itself". We don't necessarily have to 
follow HAL, but should look at is as a source of inspiration. The way 
links are represented in resources in Subbu Allamaraju's RESTful 
Webservices Cookbook [2] is another source of inspiration.

We should think of standard ways to insert links to other data into many 
common open data formats, such as xml, json and maybe even csv.. Of course 
this linking requirement is satisfied by linked open data and rdf, but 
sometimes organizations have some data and are willing to pubilsh, but 
initially do not have the necessary resources (i.e. people, knowledge) to 
develop vocabularies to describe the data. However, interlinking among 
resources of a dataset, or even linking to resources in other datasets is 
somewhat easier to do. There should be a way to at first publish open data 
resources that are linked, but without rdf, such as in xml and json. Then, 
at a later date, improve with a descriptive rdf vocabulary and expressed 
in rdf to become linked open data (preferrably, if possible, keeping 
compatibility with clients that implemented reading the previous 
non-semantic version).

Perhaps this could become a use case for the Best Practices document.

Hello DWBP,

I was reading again about the 5 Start for Open Data and I saw this 
affirmation below about 3 starts Web Data [1] that I think would be 
interesting to share with this WG.

Excellent! The data is not only available via the Web but now everyone can 
use the data easily. On the other hand, it's still data on the Web and not 
data in the Web.


With regards this affirmation, you can see more details in [2] and [3], 
but not that much.
