FOAF challenges

Some interesting discussion has been triggered by Jon Udell's comments on FOAF. I agree with Edd and Dan that FOAF is about more than social networking and have said as much here on several occasions. Personally I see two problems with FOAF neither of them big.

Firstly the name causes people to adopt certain expectations about it's intended usage particularly with general surge of interest (fad?) in social software. I certainly wouldn't advocate a name change but, as the exchange with Udell has demonstrated, we need to take care to present FOAF correctly.

The second problem is just about data. Because there is no central repository of FOAF data, it's harder to create FOAF applications: you either need to run a scutter yourself to collect up what's available, or generate FOAF out of the back-end of another site. Of course you can also hang out on #foaf and badger someone (e.g. Jim Ley or Matt Biddulph) to give you a data export; that's what I did.

I firmly believe that playing with the FOAF data that's out in the wild will generate the most interesting applications, and provide essential implementation feedback on the vocabulary itself.

So I'm going to try encouraging folk to regularly and visibly publish the results of their scutter runs. An "offical" data set hung of the FOAF homepage would also be useful. This should hopefully encourage the development of more FOAF applications.

Incidentally I mentally classify those applications as follows:

• FOAF-generating -- e.g. FOAF-a-Matic, ecademy, TypePad, etc. Applications that generate FOAF but don't typically process it to perform any useful function. These are an important step in producing a critical mass of data
  
• FOAF-gathering -- e.g. a Scutter, FOAFbot, FOAFnaut. Applications that harvest the web of FOAF data to build a data repository. Functionality is then built around this repository
  
• FOAF-consuming -- e.g. FOAF explorer/viewer, Dashboard, Planet RDF. Applications that read specific FOAF data, to fulfill some function. FOAF-gathering applications also typically consume data in this way -- to manually refresh their repository -- but I'm thinking of slightly different application scenarios, e.g. automating web site registration and preference maintenance, generating a project or community blog, etc.
  

For me this classification separates out some of the implementation issues: a FOAF-consuming application doesn't typically have to worry about attribution, trust, etc. The data is coming from a limited number of sources. FOAF-gathering applications have to deal with a much more difficult set of problems. [Lost Boy]

OpenEvents challenges

OpenEvents challenges 02/05/2005 09:12 PM

Peter Caputa puts it succinctly in

Why OpenEvents Is an Uphill Battle!

I am writing a series of posts on why OpenEvents is an Uphill Battle. I am hoping that this rallies some people to think creatively, and also to realize that if we work together to make this happen, then we will all will benefit much quicker.

So, The first reason that OpenEvents is an uphill battle is because the established players have no incentive to share data. Actually, they have disincentives because there are so many businesses that depend on the data for their revenue stream.

Whether it's XML or rdf, centralized or distributed - sharing and building on Events as an open, shared kind of micro-content - is leaving the station.

The challenges of synching

The challenges of synching 01/04/2004 08:26 PM
I predicted the other day that synching would appear in lots of newsreaders in 2004. (Some have it already, yes, but they don’t have it as I’ve defined it below.)

A good question would be: why isn’t synching already a feature of every newsreader already? It can’t be that hard, right—just read and write from a file somewhere that two copies of your newsreader can access.

I mean, what’s the hold-up? You just need something like a .newsrc. No big deal, it’s an old problem that’s been solved many times before.

Okay, so the rest of this post will be about the challenges in implementing synching.

What is synching?

First we need to define what synching is. It’s really a collection of features and requirements.

1. It’s merging, not cloning, of subscription lists.

2. It also synchs read/unread states of individual items.

3. Your newsreader uploads and downloads your synch data so you don’t have to do it manually with a browser or FTP client or whatever.

4. Your newsreader knows (or at least guesses) when it needs to download and upload synch data.

5. It works between different newsreader software on different operating systems.

I’ll take these one at a time.

Merging

Cloning is easy, merging is hard—but synching has to be merging.

For instance, imagine you have a newsreader at home and one at work. You subscribe to the same feeds—except that at work you also subscribe to some at-work-only feeds that you can’t get at home.

So when you get into work in the morning, you want to synch your data from last night at home. If it’s just cloning your subscription list, then the additional at-work-only feeds would get deleted, since you aren’t subscribed to them at home. Since we’re merging, not cloning, your at-work-only feeds do not get deleted.

But this leads to an interesting problem: what happens if you unsubscribe from a feed at home? The synching mechanism won’t delete it from your work subscription list, because for all it knows that feed could be a work-only feed.

And there’s another entire set of problems that come up because for most newsreaders the subscription list is an outline rather than a flat list. Merging hierarchies is far more difficult than merging flat lists.

Synching read/unread states of news items

This is possibly the toughest of the challenges.

In an ideal world, you can identify every item in an RSS feed with a unique id of some sort. So the synch data would be able to pair a unique ID with its read/unread status.

But not all versions of RSS have the concept of a unique ID. And, even in the versions that do have unique IDs, they’re not mandatory, and lots of feeds don’t use them. (And sometimes feeds have a terrible bug: they have unique IDs that aren’t actually unique.)

So, in the absence of a unique ID, how do you identify an item in a way that will work every single time? Answer: you can’t. There is no solution that will work every single time. (And this is why sometimes you notice in your newsreader items that are unread that you know you’ve read. They’ve been edited.)

Even if you include an entire item, all its text and links and various elements, it’s possible that the item was edited between leaving home and arriving at work.

So instead the synching has to do the best it can. Any format will probably use links and titles and whatever else so newsreaders can do a best guess. (I suspect that most developers hate situations like this, by the way, and it may be the single biggest reason why synching isn’t yet universal among newsreaders.)

Uploading and downloading

You’ll want to tell your newsreader where to save your synch data so you can get it at home and at work.

You might say, why not use .Mac? Because not everyone has an account. Because your newsreader at work might be on Windows. (And there are some other technical reasons which I’ll skip.)

Why not use FTP? Or HTTP-upload? Or...?

The answer is probably that a couple different methods may need to be made available. (FTP and HTTP-upload seem like obvious candidates, but I’m just guessing.)

But here’s the deal: I doubt that every newsreader already includes code for uploading files by the various methods people will want to use. Sure, there are libraries available, but newsreader developers will still have to write code and do a bunch of testing. Even a seemingly small thing like this still takes time and effort.

Knowing when to upload and download

This may be the easiest part.

When you launch your newsreader, it can ask if you want it to synch. It would then download your synch data from wherever and do the synch.

Similarly, when you quit, it could ask if you want to upload your synch data.

There may be more sophisticated algorithms that would make sense too, but the above is I think a good minimum.

Different newsreaders, different operating systems

This means getting a bunch of developers to agree on a format for synch data. That’s probably the easy part—the hard part will be testing to make sure X can synch with Y and Y can synch with Z and Z can synch with X.

That, by the way, is where you come in.

The Challenges Facing Bell TV

The Challenges Facing Bell TV 04/04/2005 06:22 AM
The fact that the Baby Bell telcos are now rushing to offer television over fiber is nothing new. Plenty of articles have been written about it, and it seems like this one is a little late to the game. However, it does raise some interesting points about the challenges the telcos face in reaching a point where they'll be competitive with cable TV. First, is that even after they spend billions rolling out fiber (to the home, or for the cheap Bells, the node) they have to sign the necessary content deals to have channels to offer. Since the content providers know the position the Bells are in (they absolutely need this content), the rates are going to be on the high side -- which, in turn, means that the subscription fees for end-users are going to be large, or the telcos will take some hefty losses on the service (which is exactly what's likely to happen in the short-term). However, it's also going to limit the flexibility the telcos have -- so they won't be in a position to do more creative pricing (like some of their cable competitors) to attack the market. While everyone knew that it would be easier for the cable companies to jump into the voice market than it would be for the telcos to jump into the TV market, the amount of time it's taken the telcos to act, combined with these hurdles, suggests that telco TV isn't going to be a money maker for quite some time -- if ever. At this point, the best the telcos can hope for is that telco TV will provide other benefits, such as reduced churn in other services.

AI Challenges Face the new Pope

AI Challenges Face the new Pope 04/12/2005 01:03 PM
A TechNewsWorld article presents the technology challenges that will be faced by the new Pope in the coming years. Among them is the problem of artificial intelligence. "If the Church believes strongly that a woman who has lost brain function is still alive and a fetus at its earliest stages is human, what will they think about a virtual something that emulates a person to the highest degree?" Or how about a physical something like a robot that's as intelligent as a human? Among the other technological dilemmas facing the new Pope will be cloning, cybernetics, medical technology, virtual reality, and even blogging. Considering it took them something like 250 years to apologize to Galileo and sort out that little Earth moving around the Sun thing, I hope they're up to taking on the problem intelligent machines.
