Hi Ian,

Standardised: ATOM would be perfect - What is the lists thoughts on GData?

Documented: Upcoming.org have almost no documentation at all but they do offer a wiki. Some kind of hosting space would be handy (not for us, but for you to host bits from us). I'm thinking of bits such as the weather<->Place ID list etc. I say a 'hosting space' as I'd imagine you'd have to separate it from official BBC bits.

Formats: First and foremost (for me) is XML. If I was pulling your data in Javascript I would opt for JSON. JSON has drowned YAML recently but YAML does address some of JSON's shortcomings and I believe it'll come back up for air at some point. I've never found it to be too much of a task to add alternative parsers.
Does anyone have not-so-favourable experience with YAML?

Dev System: Calls per day is going to be rather quirky in the world of widgets - It would be a shame to see something really take off and then break in the limelight. If it was too restrictive developers could look at caching themselves but that's not ideal.

Authentication: To resurrect up the recent discussion; HTTPS if it's private, key based if it's not. Then you run into distribution issues as Neil just mentioned. The easiest, fastest solution would be each developer having his own gateway :o/

Gareth Rodger

So it looks like,

RESTful
I guess XML-RPC lost out in everything except blogging and SOAP is still too painful for most people.

Standardised
So for example if we embedded everything in the ATOM syntax you would like that? Or did you mean something else?

Well Documentated.
Yep, and I really like the idea of a wiki which you guys can also edit.

Formats.
My feelings is XML makes a lot of sense. JSON, well I know its gotten much love recently but... YAML? does anyone actually use this? I thought JSON did away with YAML?
Also who's offering this as a webservice?

Developer system
Yes we will require some kind of authentication system and I guess this is where the real debate goes. What kind of interactions would you prefer?

How would you feel about us having some developer key system, maximum amount of calls a day, authentication?

What have you seen which you like?

I remember Flickr was a pain because you couldn't find your dev key easily, while Amazon had a dev token and authentication. Technorati's limit of 1000 calls a day is ok but how do people feel about the result once you go over the limit? Should error messages use http states or return errors in xml?

Thoughts?

Subject: Re: [backstage] The best WebAPIs

I must agree with the Flickr fans.

In my opinion if it's;
RESTian
Standardised
Well documented
Choice of output formats (JSON, YAML, XML etc.)
An open wiki to supplement the docs
It'll do for me.

Will the BBC require developer keys or authentication?.

I really like the flickr because they offer a simple api for non- techies in the form of the badge, which even my dad can use (this is a man they type with one finger and that's not one finger on each hand but just one finger).

This makes the content really accessible which is important.

And on the other end of the spectrum they offer api's that for the true developer that allow you to achieve things like this
http://www.webmonkey.com/webmonkey/06/08/index4a_page2.html

For me this is awesome becuse it not only shows their content up in a good light. It promotes flickr and can inform their service development; all things that I think backstage is trying to do for the BBC.

Important things that I have found useful but may not fall into the realm of api for some people is:

For the novice:
Restful/guessable/hackable URLs
A range of simple standard RSS feeds
Examples and easy to use interfaces eg: flickr badge

For the not so novice:
Parameterised RSS feeds
HTTP implemention is always good but the technology in my opinion should be the one that can be used by the most people. Good documentation and often the best documentation is not found on the providers site but on people's blogs, so making the documentation an open wiki would help.

Lets put the debate on hold for now (although I was tempted to throw in a line about the GPL3 drafts). I don't know about everyone else, but I personally think this could make a good podcast if I got a few of you in
a room together.


Anyway,

Its almost 2007 and I wanted to ask a question to the list.

One of the things you really want more of, is more BBC API's. Well were working on that but I wanted to ask which API's have you used which were
a joy to use and why?
Is the documentation, API naming, structuring, amount of data given away
or something else?

For example, for me Flickr's API is great but I love the security of
Del.icio.us. The documentation on Flickr is also very easy to follow and understand while the ability to run XSL serverside on Amazon's servers
has been useful. Google Data/Base is very interesting being just ATOM
based and I can certainly see more APIs using ATOM as a base result
response in the future.


Don't worry guys we can pick up the Free Software debate later...
