Books, LibraryThing and me

Joss Winn / / Fun, Identity

We recently planned, designed and built our own, small, house. Once the builders had gone, I finished off the interior, laying the finished floors, decorating and tiling. I also put up book shelves that went up one side of the back door, over it and then down the other side, so that when you walk through the door, you walk under our books. There’s about 500 or so, I guess.

Why am I writing about this? Well, those books, accumulated by my wife and I over many years, look good against the wall there, and when people visit, they often stand looking across the shelves at the range of books we’ve bought and sometimes even read. Personally, I buy books on a whim and there are many that I’ve yet to read. I rarely read books cover-to-cover and rarely read fiction. When you look across the shelves, tilting your head to read the spines, you’ll come across the fiction I started reading in my late teens, the books on Buddhism, philosophy and Japanese, that I bought as a student; you’ll see the books I bought while a post-graduate student, studying film archiving. Then there are all the books I bought in-between, while teaching myself about computers, not to mention all my wife’s books. I don’t know about you, but those books say a lot about me and about the last 20 years of my life. Many of them reflect my interests and ambitions before I sent my first email, before I first used the World Wide Web and before I knew 70% of the people I now call ‘friends’ (such an abused word these days).

The thing is, I haven’t opened many of those books since I first looked at them. I’ll never read them again and most of the people I know at work and online, will never scan my bookshelves. We can chat over Twitter, subscribe to each other’s FriendFeed and read each other’s blogs, but I’ll tell you now, that’s not even half of me.

I signed up to LibraryThing a couple of years ago, added a couple of Cormac McCarthy books and then left the account alone. I thought my wife would enjoy it more than me. She reads books cover-to-cover all the time. I don’t. I use books to learn about things that I don’t know. With the exception of a few authors, I rarely read books for relaxation. I relax in my own time online and have done for years. It suits my wandering mind.

It occurred to me a few days ago that LibraryThing could enrich my digital identity in a way that no other social networking site could. By importing my book collection into LibraryThing, I could go back over my book collection, dust off the covers and gradually enrich my online identity, and at the same time people would get to know me better, if they cared to look. Never mind Twitter, where I’ve read that we’ll get to know one-another through a glimpse of the small details of our lives. I don’t buy it. You’ll learn more about me by perusing my LibraryThing collection, I can assure you.

As I write this, I’ve added 110 books that I own, about a third of the total, I reckon.

This also got me thinking about e-portfolios and how the books I accumulated as a student reveal a lot more than my CV about my depth of study and research interests during and shortly after those periods of learning. To build a book collection over time is an achievement in itself. We tend to think of a portfolio as an accumulated, curated presentation of work that we have undertaken. It’s a product – something to show; but until recently we couldn’t include a book collection in our portfolio.

As a student, I spent more time reading than writing and I read wider than my term papers and exams reflected. Despite a good degree, my undergraduate essays aren’t worth your time today, even if I could still find them, but I still have the books I collected and they are worth your time. If I was employing me, I’d take an interest in my book collection. It’s a background check I can recommend.

Of course, I could have added books I don’t own to give a false impression of myself (I haven’t). And I could exclude books from LibraryThing that I do own, because they might give a false impression of who I think I am (I have – the exceptions are trivial). But this is my point about Identity and LibraryThing: I’ve got a collection of physical books that I’m now curating online to develop a ‘portfolio’ that better represents me.

I guess that’s what a lot of LibraryThing members do. Have you?

Developing BuddyPress for education

Joss Winn / / Open Source, Software, Web

In February, I wrote a brief post about setting up BuddyPress with LDAP authentication within a university context (you’re looking at it). Four days ago, BuddyPress reached maturity by hitting version 1.0, marking a time to reflect on what I’d like to see developed for BuddyPress for use within a university context. This is an initial wish list. I’m not looking for BuddyPress to be an all singing, all dancing, social network. I don’t care about image collections and status updates (Flickr and Twitter do those jobs nicely) I would, however, like to see it being used for building group identity (projects, special interest groups, classes, courses) and portfolio/resume building. Right now, it’s pretty limited in those areas.

Privacy controls

As I mentioned previously, our social network is private, while the blogs have five levels of optional privacy controls, ranging from public and indexed by Google, to private, single-user blogs. However, privacy within the social network is currently all or nothing. It’s a hack that works but has no flexibility. The BuddyPress activity plugin is currently turned off because the privacy plugin I use, doesn’t account for the feeds that the plugin exposes. It would be nice to be able to have the site-wide social activity visible when logged in. Currently, only information about new blog posts is published site-wide. What I would like is for everything that the activity plugin logs, to have site admin options to be 1) visible to non-logged in users/public; 2) visible to logged in users; 3) visible to my groups and friends,4)  visible to my friends and 5) not visible. In addition, the feeds that are exposed of site-wide activity and member activity, could also be configurable so that 1) a site admin can choose to expose them or not; 2) if allowed, a member can choose to expose their personal feed or not; 3) a feed key could be used in place of the normal feed URI so that private member feeds could be created. Finally, groups and member profiles could optionally be made public or private. So anything following /groups/ or /members/ has an option to be visible outside the community.

Group activity

Currently, groups don’t publish very much information and you can’t aggregate information from elsewhere into a group profile. I submitted a ‘wishlist’ ticket to BuddyPress for group activity feeds, requesting that feeds for when a new group member joins and changes to the group wire. It would also be nice to be able to aggregate content from other sites via RSS into the group ‘news’ field, or a new lifestream-like field so group photos or videos or whatever, could be sucked in. It was possible to do this via a Yahoo! Pipe which combined various feeds which could then be put through feed2js and dropped into the ‘News’ field. However, embedded javascript is now intentionally blocked 🙁 I guess I could find a work-around.

Member profiles

For both teachers and students, the profile pages could be effective resumes. Currently, the site-admin can build basic grouped fields and there’s a choice of field types, too. I’d like members to be able to build their own fields and for there to be pre-built field types to choose from. It’s possible for the site admin to pre-build fields and probably easy enough for me to pre-build specific fields to design a resume (the examples given of language, country and state are just .csv lists). However, currently, if I provide three ‘Employment’ fields, a member can’t add a fourth ‘Employment’ field, nor can they select dates to correspond to when that employment was. I’m pretty sure I could create the fields, but it’s beyond me to allow a member to build their own profile pages from a selection of pre-built fields.

Finally, in addition to my request for members to be able to make their profiles public, I’d like the member profile to be marked up with hResume markup and exportable in a variety of styled formats: xhtml+css, xml, pdf, txt, doc and rtf.

The entire member profile should use microformat markup where possible. Currently, the profile can export a simple, personal hCard but could also use hCard for company and school addresses, hCalendar for dates, and rel=”tag” for creating a set of tagged skills. LinkedIn partially implements this, by the way.

So, privacy controls, group feeds and a resume builder. Not too much to ask is it? I’d probably be able to pay for the resume builder if anyone is interested…

Pimping your ride on the semantic web

Joss Winn / / Fun, Identity, Standards & Specs, Tips, Web

Yesterday, I wrote about how I’d marked up my home page to create a semantic profile of myself that is both auto-discoverable and portable. A place where my identity on the web can be aggregated; not a hole I’ve dug for myself, but an identity that reaches out across the web but always leads back home.

While I enjoy polishing my text editor regularly and hand-crafting beautifully formed, structured data, we all know it’s a fool’s game and that the semantic web is about machines doing all the work for us. So here’s a quick and dirty run down of how to pimp your ride on the semantic web with WordPress and a few plugins.

You’ll need a self-hosted WordPress site that allows you to install plugins. I’ve got one on Dreamhost that costs me $6 a month. Next, you’ll want to install some plugins. I’ll explain what they do afterwards. One thing to note here is that I’m using plugins from the official plugin repository whenever possible. It means that you can install them from the WordPress Dashboard and you’ll get automatic updates (and they’re all GPL compatible). In no particular order…

I think that’s quite enough. All but the SIOC plugin are available from the official WordPress plugin repository. Here’s what they provide:

APML: Attention Profile Markup Language

APML (Attention Profiling Mark-up Language) is an XML-based format for capturing a person’s interests and dislikes. APML allows people to share their own personal attention profile in much the same way that OPML allows the exchange of reading lists between news readers.

The plugin creates an XML file like this one that marks up and weighs your WordPress tags as a measure of your interests. It also lists your blogroll/links and any embedded feeds.

Extended Profile

This plugin adds additional fields in your user profile which is encoded with hCard semantic microformat markup and can then be displayed in a page or as a sidebar widget. You can import hCard data, too. There might also be another use for this, too. (see below)

Micro Anywhere

Provides a couple of additional editor functions that allow you to create an hCard or hCalendar events page. Here’s an example.

OpenID

This plugin allows users to login to their local WordPress account using an OpenID, as well as enabling commenters to leave authenticated comments with OpenID. The plugin also includes an OpenID provider, enabling users to login to OpenID-enabled sites using their own personal WordPress account. XRDS-Simple is required for the OpenID Provider and some features of the OpenID Consumer.

This is key to your identity. You can use your blog URL as your OpenID or delegate a third-party service, such as MyOpenID or ClaimID. In fact, you’ve almost certainly got an OpenID already if you have a Yahoo!, Google, MySpace or AIM account. It’s up to you which one you choose to use as your persistent ID. Read more about OpenID here. It’s important and so are the issues it addresses.

XRDS-Simple

This is required to add further functionality to the OpenID plugin. It adds Attribute Exchange (AX) to your OpenID which basically means that certain profile information can be passed to third-party services (less form filling for you!) Like a lot of these plugins, install it and forget about it.

SIOC

Provides auto-discoverable SIOC metadata. “A SIOC profile describes the structure and contents of a weblog in a machine readable form.”

wp-RDFa

Provides an auto-discoverable FOAF (Friend of a Friend) profile, based on the members of your blog. I’ve been in touch with the author of this plugin and suggested that the extended profile information could also be pulled into the FOAF profile. This is largely dependent on the FOAF specification being finalised, but expect this plugin to do more as FOAF develops.

OAI-ORE Map

Provides an auto-discoverable OAI-ORE resource map of your blog. It conforms to version 0.9 of the specification, which recently made it to v1.0, so I imagine it will be updated in the near future. OAI-ORE metadata describes aggregated resources, so instead of seeing your blog post permalink as the single identifier for, say, a collection of text and multimedia, it creates a map of those resources and links them.

LinkedIn hResume

LinkedIn hResume for WordPress grabs the hResume microformat block from your LinkedIn public profile page allowing you to add it to any WordPress page and apply your own styles to it.

I like this plugin because you benefit from all the features of LinkedIn, but can bring your profile home. Ideal for students or anyone who wants to create a portfolio of work and offer their resume/CV on a single site. Depending on the theme you use, it does require some additional styling.

Get_OPML

This is a nice way to create an OPML file of your sidebar links. If, like on my personal blog, your links point to resources related to you, you can easily create an OPML file like this one. There’s a couple of things to note about this plugin though. The instructions mention a Technorati API key. I didn’t bother with this. When you create your links, just scroll down the page to the ‘advanced’ section and add the RSS feed there. Secondly, the plugin author has, for some stupid reason, hard-coded the feed to their own site into the plugin. Assuming you don’t want this spamming your personal OPML file, download a modified version from here or comment out line 101 in get-opml.php. I guess the plugin author thinks that you’ll be using this to import the OPML into a feed reader and from there, you can delete his feed. That’s no good to us though. Finally, you’ll want to make your OPML file auto-discoverable. You can do this by adding a line of html in your header, using the Header-Footer plugin below.

Header-Footer

This simply allows you to add code to the header and footer of your blog. In our case, you can use it to add an auto-discovery link to the header of every page of your blog.


<link rel="outline" type="text/xml+opml" title="ADD YOUR TITLE HERE" href="http://YOUR_BLOG_ADDRESS/opml.xml" />

WP Calais * + tagaroo

These three plugins use the OpenCalais API to examine your blog posts and return a bunch of semantic tags. I’ve written about this in more detail here (towards the end).

The Calais Web Service automatically creates rich semantic metadata for the content you submit – in well under a second. Using natural language processing, machine learning and other methods, Calais analyzes your document and finds the entities within it. But, Calais goes well beyond classic entity identification and returns the facts and events hidden within your text as well.

It’s an easy way to add relevant tags to your content and broadcast your content for indexing by OpenCalais. They place an additional link in your header that lists the tags for web crawlers and, I guess, improves the SEO for your site.

Extra Feed Links

I’ve written about this plugin previously, too. It adds additional autodiscovery links to your blog for author, category and tag feeds. WordPress feed functionality is very powerful and this plugin makes it especially easy to make those feeds visible.

Lifestream

This isn’t a semantic web plugin, but is a powerful way of aggregating all of your activity across the web into a single activity stream. See my example, here. It also produces a single RSS feed from your aggregated activity. Nice 😉

Wrapping things up

If you set all of this up, you’ll have a WordPress site that can act as your primary identity across the web, aggregates much of your activity on the web into a single site and also offers multiple ways for people to discover and read your site. You also get a ‘well-formed’ portfolio that is enriched with semantic markup and links you to the wider online community in a way that you control.

Bear in mind that some of these plugins might not appear to do anything at all. The semantic web is about machines being able to read and link data, right? If you look closely in the source of your home page, you’ll see a few lines that speak volumes about you in machine talk.


<link rel="meta" href="./wp-content/plugins/wp-rdfa/foaf.php"type="application/rdf+xml" title="FOAF"/>
<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:dc="http://purl.org/dc/elements/1.1/">

<link rel="resourcemap" type="application/atom+xml" href="http://blog.josswinn.org/wp-content/plugins/oai-ore/rem.php"/>

If you do want a way to view the data, I recommend the following Firefox add-ons

Operator: Auto-discovers any embedded microformats and provides useful ways to search for similar data via third-party services elsewhere on the web.

OPML Reader: Auto-discovers an OPML file if you have one linked in your header. Allows you to either download the file or read it on Grazr.

Semantic Radar: Auto-discovers embedded RDF data. Displays custom icons to indicate the presence of FOAF, SIOC, DOAP and RDFa formats.

The Tabulator Extension: Auto-discovers and provides a table-based display for RDF data on the Semantic Web. Makes RDF data readable to the average person and shows how data are linked together across different sites.

As always, please let me know how this overview could be improved or if you know of other ways to add semantic functionality to your WordPress blog. Thanks.

Microformats and Firefox

Joss Winn / / Fun, Standards & Specs, Web

When I have time, I like to read about new and developing web standards and specifications. Sad, you might think, but it’s a way of learning about some of the theoretical developments that eventually turn into practical functionality for all users of the Internet.  Also, I am an Archivist (film, audiovisual, multimedia) by trade, and am somewhat reassured by the development of standards and specifications as a way of achieving consensus among peers and avoiding wasted time and effort in managing ‘stuff’.

So, while poking around on Wikipedia last night, I came across ‘Operator‘, an add-on for Firefox that makes part of the ‘hidden’ semantic web immediately visible and useful to everybody. If you’re using Firefox, click here to install it. It’s been available for over a year now and is mature and extensible through the use of user scripts.  It’s been developed by Michael Kaply, who works on web browsers for IBM and is responsible for microformat support in Firefox.

Operator leverages microformats and other semantic data that are already available on many web pages to provide new ways to interact with web services.

In practice, Operator is a Firefox tool bar (and/or location/status bar icon) that identifies microformats and other semantic data in a web page and allows you to combine the value of that information with other web services such as search, bookmarking, mapping, etc. For example, this blog has tags. Operator identifies the tags and then offers the option of searching various services such as Amazon, YouTube, delicious and Upcoming, for a particular tag.  If Operator finds geo-data, it offers the option of mapping that to Google Maps and, on this page for example, it identifies me as author and allows you to download my contact details, which are embedded in the XHTML. Because it is extensible through user-scripts, there are many other ways that the microformat data can be used.

Of particular interest to students and staff are perhaps the microformat specifications for resumes and contact details. Potentially, a website, properly marked up (and WordPress allows for some of this already), could provide a rich and useful portfolio of their work and experience which is semantically linked to other services such as Institutional Repositories or other publications databases where their work is held.

After using it for a few hours, I now find myself disappointed when a website doesn’t offer at least one piece of semantic data that is found by Operator (currently, most don’t but some do). Microformat support will be included (rather than an add-on) in Firefox 3.1 and IE 8, so we can expect to see much more widespread adoption of it. A good thing.

There’s a nice demonstration of microformats here, using the Operator plugin.
