It’s a very vibrant space right now, with commercial vendors, open source projects, trends, and standards all vying for attention. I’m thinking here of a couple of overlapping categories:

OpenID

A standard, for which there are good open source libraries, but also commercial providers. Increasingly I’m seeing OpenID as one service (often the anchor service) provided as part of a suite. Of course the traditional mainstream web players like LiveJournal, WordPress.com, Yahoo! and AOL (through AIM) are providing OpenIDs as well.

Lifestream and Profile Aggregation

More social networks == more profiles, and more feeds. A number of services/projects have sprung up (I talk about a few below, but there are many others as well) which enable you to aggregate together all of your profiles in a single place. Some are more focused on aggregating all of your feeds – creating your lifestream and letting others subscribe to it; others are focused on aggregating the feeds of your friends, to make it easier for you to follow.

The Data Portability Project, Open Web Foundation, Open Social Foundation, Autonomo.us

These foundations are not focused (directly) on producing software, but on building awareness of and consensus about the need for user freedom on the internet, and publishing open specifications which will lead to a world in which our online identities and data streams can be more easily managed, exchanged, and even migrated from provider to provider.

It would really be a full-time job to keep track of all that is going on in this space, but here are a few I’ve been following / trying out.

Chi.mp

Chi.mp enables each user to create their own domain in the .mp TLD space. You can check out mine at johneckman.mp. Chi.mp provides OpenID, but doesn’t (yet) consume it. (I can use johneckman.mp as an OpenID to log in to other sites, but I can’t login to chi.mp with an OpenID from elsewhere).

Chi.mp also supports a number of services (currently Twitter, Facebook, Flickr, Gmail, Yahoo (mail), and Hotmail). For those which provide activity feeds, chi.mp will pull those feeds into your profile (viewable by others) and dashboard (viewable only by you). There’s also a generic RSS feed import capability, for services (like personal blogs) that Chi.mp doesn’t know.

Finally, Chi.mp also supports your social graph – your friends lists or contacts lists from various services can be imported – from webmail services like gmail and hotmail but also from services like Twitter, Facebook, and Flickr which have contacts or friends exposed via an API.

It’s very highly configurable, in terms of who can see what. You can tag contacts, and tag feeds, and use tags to determine visibility of feeds to groups of contacts. I haven’t yet really figured out what else Chi.mp will be able to do with webmail services – I don’t think I will ever want emails I send or receive showing up in my action stream or on my profile, but certainly being able to leverage various APIs for getting contacts will reduce the need to “refriend” people on each new network.

For now, however, Chi.mp has no way to identify that the “John Doe” you are friends with on facebook is the same person as the “John Doe” who is a contact on Flickr – they provide a simple way to manage contacts (and “merge” the two contacts into one virtual person) but there is still human effort (decision making) involved in reconciling these graphs.

Trufina

Trufina adds an interesting twist in that they are trying to more tightly link online identity to offline. Using a method well known to financial services companies – the ability to answer a short set of questions about your financial history which would not be known to someone who found your wallet in the street – Trufina verifies that the person using the name John Eckman is the same one who lives at a given address and has other “meat space” attributes.

You can see my default public profile here:

I have to say their focus on “criminal background checks” I found a bit creepy: I realize that background checks are important for certain kinds of employment, but it seems like the need (and even desire) to assert a record free of felony convictions should be a niche market, not the default market for an online identity vendor. (Employment verification and educational background verification are said to be in development).

They also then enable you as a user to share various parts of your verified identity with others, including inside a number of social networks. You can create an “ID Card” and show that to only specific folks. There was no way I could find, however, to not show the “Criminal Records Search” section of the ID Card – it seems to always show either “” or “ ” – neither of which makes for high confidence. How about the ability to not show that section at all, if I don’t think it’s relevant, in which case you could also dispense with the rather elaborate disclaimer about criminal record checks.

I also found it frustrating that the default “profile” view – the only one people can get to who haven’t been specifically authorized by you – shows only the Trufina user name. Obviously given the market Trufina is after, and the data that a full profile might ultimately contain, they need to be concerned about privacy. But what if I’m perfectly happy to have people see my first and last name and maybe state of residence and employment?

The key to privacy needs to be control, not defaults which prevent users from making basic data public.

Identity.net

The folks at Identity.net have partnered with Trufina, to link your “Trufina Verified Identity” to an OpenID which can be used throughout the web. It’s a great concept – to be able to demonstrate that the virtual identity a given OpenID represents is tied to a real offline person could be quite valuable.

I’d hope to preserve, however, the option to also have OpenIDs which are not linked to my offline identity. The ability to get the benefits of OpenID (in terms of single-sign-on) without necessarily having all online activity tracked directly to your offline identity is one of the freedoms the internet promises and I’d hate to lose that. (A number of OpenID providers enable you to create multiple OpenIDs that only they know are associated with each other – this enables you to project different identities on different sites).

Like many of these services, Identity.net is in beta, and was having trouble with their control panel when I signed up, so it’s possible I haven’t yet seen what flexibility they offer in creating and using OpenIDs tied to your Trufina identity.

ClaimID.com

I use ClaimID with delegation to use JohnEckman.com as an OpenID. ClaimID also provides a basic profile page on which you can enter links to web sites and verify your ownership of them, as well as display contacts, optionally marked up in XFN (with semantic data about the relationship you have with each contact).

Movable Type with Action Streams Plugin

I use the open source edition of Movable Type with the Action Streams plugin to power JohnEckman.com as a lifestream aggregator, pulling in feeds from various web services. Creating additional plugins to add services to Action Streams is relatively simple, and I’m hosting it myself so I have complete access to the data stored and complete flexibility in display.

The DiSO project has produced a similar plugin (WP-DiSo-ActionStream) for pulling action streams into WordPress (I’m using the OpenID plugin from DiSO on this blog), and there’s an Activity Streams module available for Drupal as well.

Finally, there’s Sweetcron, which I have only just started to experiment with, but which focuses on just managing the action stream aggregation without the extra functionality (and overhead) of a blog or other framework like MT, WordPress, or Drupal. It’s also easily extended.

As all of these evolve, how much ownership and control will users want to have over the content their online activity produces? How much technical understand and effort will they be willing to expend in order to exert that control?

What, in other words, will be the balance between hosted providers (they do all the work but also retain some element of control) and self-hosted open source platforms (you do more work and gain more control)?

Will the central difference between the two options lessen as real data portability becomes commonplace?

The problem is that when I send brightkite a message like: @bos

It sometimes knows that is Logan Airport in Boston, and sometimes just knows that as BOS, United States, which results in updates like this:

Anyone know why this is happening? Brightkite’s fault? Fire Eagle’s fault? Neither?

Update: Should perhaps have checked first. Brightkite seems to be working on this issue, at least according to this post on GetSatisfaction. Seems like they recognize some airport shortcodes but may not always have the full name associated with it and what city/state they are in.

Since my FireEagle feed only updates with city level info, you can’t see that it is an airport.

Hopefully this will mean fewer “United States” updates in my feed over time.

It’s basically a roll-your-own lifestream, though for now at least it isn’t integrated to anyone else’s streams, as in Friendfeed or Socialthing.

This morning I posted a new plugin which picks up TripIt Activity Streams.

TripIt’s activity stream is a private Atom feed which posts an item whenever you begin a trip, complete a trip, or start planning a trip. For example, here’s a recent entry from my feed:

You can download the plugin from the MTAS page.
