I just posted the slides for my ApacheCon US 2007 talk on the ApacheCon wiki. It's basically the same talk that I gave at ApacheCon EU earlier this year, but I spent some time tweaking the slides, simplifying removing unnecessary bits and adding a little Abdera coverage. That, and the fact that the power did not fail, seemed to make the talk go more smoothly this morning. Here are the slides:

Apache Roller and blogs as a web development platform (2MB PDF)

Apache member Brian McAllister, who works for Ning, has proposed a new project for Apache called Shindig. Here's an excerpt from the proposal:

OpenSocial provides a common set of APIs for social applications across multiple websites. With standard JavaScript and HTML, developers can create social applications that use a social network's friends and update feeds. A social application, in this context, is an application run by a third party provider and embedded in a web page, or web application, which consumes services provided by the container and by the application host. This is very similar to Portal/Portlet technology, but is based on client-side compositing, rather than server. More information can be found about OpenSocial at http://code.google.com/apis/opensocial.

Shindig is an implementation of an emerging set of APIs for client-side composited web applications. The Apache Software Foundation has proven to have developed a strong system and set of mores for building community-centric, open standards based systems with a wide variety of participants. A robust, community-developed implementation of these APIs will encourage compatibility between service providers, ensure an excellent implementation is available to everyone, and enable faster and easier application development for users.

. . .

Ning, Inc. intends to donate code based on their implementation of OpenSocial. The backend systems will be replaced with more generic equivalents in order to not bind the implementation to specifics of the Ning platform.

Brian is pretty excited about OpenSocial as a light-weight client-side alternative to Portal/Portlet technology, not just for social apps but for webapps of all kind. He'd like to see both Apache Roller and Apache JSPWIki (incubating) become OpenSocial containers, despite the fact that neither product stores the social graph of user/friend relationships. Blogs and wikis are already great platforms for web development, OpenSocial could make them even stronger. Very interesting stuff.

I hadn't planned on talking OpenSocial during my session tomorrow, but I might have to add a slide or two to illustrate the possibilities.

Tri-LUG announcement: Pat Patterson from Sun Microsystems will provide us with a developer perspective on digital identity, starting from the emergence of LDAP in the 90s, through single sign-on, SAML and the Liberty Alliance protocols to recent developments such as OpenID, Cardspace and OAuth. The emphasis will be on understanding the protocols and how they are implemented in the real world, with a particular focus on deciding which (if any!) approach to select for a given project.

Pat Patterson is a federation architect at Sun Microsystems, focusing on federation, identity-enabled Web services and OpenSSO, Sun's open-source implementation of those technologies. Pat's blog centers on identity-related topics.

Looks like a great talk and I've always wanted to meet SuperPat, so I'll be there.

Here are the details:

Speaker:   Pat Patterson
Title:     Digital Identity from LDAP to SAML and beyond

Matt Raible, Don Brown and I will be doing at "Roller and Struts 2" birds-of-a-feather (BOF) session on Wednesday night at ApacheCon at 8:30PM. Thanks to Atlassian for sponsoring the beer-of-freeness (BOF). The sign-up is here:

There are already handful of people signed up, so I guess I better work on some preso materials. I'll be prepared to talk about Roller status, future plans and Roller's recent migration from Struts 1 to 2.

Are there any specific Roller issues you'd like to discuss in the BOF?

Another batch of social software related links today, but today it's all about Google's new OpenSocial APIs (link to go live tomorrow). I waded through 20 or so posts today and the links below are my favorites. Gotta say, I'm really looking forward to getting the details tomorrow, understanding how Roller can play and seeing how AtomPub fits into the picture -- and I'm assuming it does since GData has been mentioned (see the Brady Forrest link below). After reading Marc Andreessen's post, which is the first link below, I think it's possible that Roller could act as both a Container and as a provider of Apps for other Containers. I wonder, could OpenSocial provide the UI widget API that Roller needs? And, will Roller's rather limited user profile data be enough to allow Roller to act as a Container? If so, I might be doing some late night hacking this weekend.

• Marc Andreessen: Open Social: a new universe of social applications all over the web
  "An open web API that can be supported by two kinds of developers: Containers -- social networking systems and... Apps -- applications that want to be embedded within containers"
• Brady Forrest: Google Announces the OpenSocial API
  "The open API will have three parts People, Storage [and] Activity stream. All of these calls will have a GData counterparts"
• Fred Stutzman: On OpenSocial
  "It's unfortunate that Google, rather than a standards body, is at the center, but perhaps this will outline a standard way forward"
• Danny Ayers: Google's OpenSocial coming tomorrow
  "Will this stuff be truly open, usable as linked data (with appropriate authentication) or will it still be hogtied within those partners' environments?"
• Valley Wag: What OpenSocial will look like on LinkedIn
  "Here are screen shots detailing how one such partner, LinkedIn, plans to incorporate apps"

Some reading on Facebook and enterprise social software from my del.icio.us bookmarks collection:

• Tim Bray: The Intimate Internet
  Bray on Facebook: "Twitter hits that 80/20 point, bringing me that news without all the Facebook bullshit and lame groups and dorky apps and stupid ads and data lock-in. "
  
• Fred Stutzman: The Directionality of Social Network Platforms
  Stutzman on Facebook: "the ecosystem needs more than fluff, especially if we're going to start talking about the "social operating system."
• Phil Windley: What's wrong with Facebook
  Windley on Facebook: "social Webs will require similar attention to the structure that emerges from social activity, not nagging people about it";
• Doc Searls: Too much face(book) time
  Searls on Facebook: "If you're waiting for me to respond to a poke or an invitation, or a burp or any of that other stuff, don't hold your breath."
• Read/Write Web: Big Vendors Scrap for Enterprise 2.0 Supremacy
  "The [products] remain complex and broad in scope - which in many respects goes against the grain of simple and easy-to-use web 2.0 products."
• Personal InfoCloud: The State of Enterprise Social Software
  "Nearly all of the enterprise software product companies are claiming understanding of Web 2.0, but none execute well on it"

That was the only complaint the kids had about the They Might Be Giants show last night, their first "real rock concert" as they called it. Otherwise they loved it. My brother and I took Alex (10) and Linus (9) to the show at the Carolina Theater in Durham. They had a great time, pogoed around like the rest of the crowd and didn't get to bed until after 1AM.

I loved the show too. The last time I saw TMBG was probably before you were born; just the two Johns with a guitar, accordion, saxophone and a jam-box playing a drum tape. This time they had a full rock band with an amazing guitar player but unfortunately, no horns. They put on a solid show, played a wide variety of songs not weighted too heavily to their latest release, The Else, which was good and bad. Good because they've got a giant back catalog of kick ass jams. Bad because we've been listening to The Else and the boys really dig Bee of the Bird of the Moth -- guess they needed the horns for that one.

Here are some related links: There are still about 20 shows left in the TMBG tour. David Menconi of the Raleigh N&O blogged about TBMG and scored an interview. And Pat Mueller remarks on the nerd-fest that is the TMBG audience.

Matt Raible gave a talk today at the Colorado Software Summit on integrating Roller with LDAP and CAS. He also has provided some nice notes on that and running Roller on Geronimo:

• Roller 4.0 with LDAP and CAS
• Roller 4.0 on Geronimo

Matt had to make a couple of tweaks to get thing going with Roller 4.0 RC8 and a couple other problems have been found, so you can expect RC9 shortly.

ApacheCon US 2007 is only about 20 days away. I'm getting psyched up to do my Roller and blogs as a web development platform talk again (and thinking about topics for ApacheCon EU 2008). There's still plenty of time for you to register and attend. And Apache fans, please grab a banner and help promote ApacheCon on your project site and blogs.

Joe Cheng posted another entry in his series explaining the details of AtomPub support in Windows Live Writer (WLM), titled WLW+AtomPub, Part 2: Authentication.

Wondering what WLM looks like? Travelin' Librarian has a nice set of screen-shots of WLM on Flickr including shots of the installation process, HTML mode, preview mode and more. Looks pretty sweet.

RSS advistory board: The RSS Profile makes it easier for feed publishers and programmers to implement RSS 2.0, offering advice on issues that arise as you develop software that employs the format. For 18 months, the board worked with the RSS community on interoperability issues, receiving help from representatives at Bloglines, FeedBurner, Google, Microsoft, Netscape, Six Apart and Yahoo. The profile tackles the most frequently asked questions posed by developers:

1. How many enclosures can an item contain?
2. Are relative URLs OK in item descriptions?
3. Is it OK to use HTML in elements other than an item's description?

For the answers, read the sections on enclosures, item descriptions and character data, respectively. Sam Ruby announced this morning that the Feed Validator now tests for conformance to the profile, offering 11 new checks for improving interoperability.

Kudos to the RSS Advistory Board. The RSS Profile is an excellent guide to publishing RSS. Plus, it's very nice to see the confusing parts of RSS clarified and to see those clarifications linked to from the RSS spec.
