Going back to basics, the four point could be crashed into two

a)      Use URIs to name and to point into things (resources)

b)      Provide useful information as links (metadata, origin, etc)

Note that one URI could have many variants: languages, formats, time (memento), etc. So

Get the "best" variant


Get the useful information


Get some specific variants




It is very refreshing to type an URI and get the "thing", even if sometimes one would prefer a forgetful  web :)

As you can see, it is a subject with some pedigree.

Steve, Manuel,
I am not talking only about the Resources. Or, what are the things that are exposed as Resources.
For example, in DBpedia there is a Resource for the album Houses of the Holy (http://dbpedia.org/page/Houses_of_the_Holy).
There is also a Resource for the record label Atlantic Records (http://dbpedia.org/page/Atlantic_Records), which is the record label from the album Houses of the Holy.
What is the URI of all albums of the record label Atlantic Records?
My question is: could it be one Best Practice, recommended by of DWBP WG, to provide a way of exposing the "Resource" All Albums of the Record Label Atlantic Records?
Best Regards,

Thanks.  A few people have agreed with our position below, but some still like the idea of API's for accessing Data.  What is the process W3C uses to resolve these points of view and when it is resolved, does the conclusion get written into the Best Practices draft and/or do we also include the lineage of the conclusion - that is, we we present the pros and cons and reasons for the conclusion by also relating what we didn't recommend and why?

RE: APIs to work with data on the web



-        Resources should be addressable with a URI
-        One should aim a common interface for humans and machine

Excellent use case which begins to explore and spell out the advantages and trade-offs of using API's to access Open Data.  I would like to explore this topic in greater detail.  My own personal preference is data access by HTTP and URI, because it provides a common interface for humans and machines.  But are there performance implications?

RE: APIs to work with data on the web


Hi all,

Very interesting article indeed and related to discussions we’re currently having with developers as part of Open Data Ireland on how best to publish/use machine-readable data.

I’ve added a use-case on it https://www.w3.org/2013/dwbp/wiki/Use_Cases Please feel free to add points or pick up on nuances of the conversation that I missed. Perhaps we could break this into multiple use-cases to look at each of the aspects in more detail?

Hi Laufer, I didn't know the Socrata.
Thanks for share the link, Makx. Very interesting text and point of view about APIs.

Subject: APIs to work with data on the web

Hi all,

         Last week, Yaso and I were talking about APIs and how they are important in all aspects of data on the web. APIs are one of the simplest ways to access and to distribute data across the web, and we think that is an important subject to be discussed on the WG.
         To talk about APIs, we obviously need to discuss about URI and descriptors. Carrasco written the first document [1<http://www.w3.org/2013/dwbp/wiki/Data_on_the_Web_URI_Best_Practices>] about it, besides there are a few messages discussing it.
         Moreover, I want to share some links I consider relevant and useful to discuss about this topic.
         Joshua Bloch, a software engineer and former Googler, published an article on InfoQ [2<http://www.infoq.com/articles/API-Design-Joshua-Bloch?utm_source=buffer&utm_campaign=Buffer&utm_content=buffer36801&utm_medium=twitter#.UvbdCPy0BT0.delicious>] site and made a presentation called “How to Design a Good API & Why it Matters” [3<http://www.infoq.com/presentations/effective-api-design>] (other Jushua's presentation about the same subject, but the video is hosted on YouTube [4<https://www.youtube.com/watch?v=aAb7hSCtvGw>]). These links are very interesting and I recommend to all of you, even who is already expert in API design.
