alley with sematag

There is a great need for the data model supported by the WWW to be extensible. The WWW data model could be roughly described as a text model formalized by HTML which embeds other data or live objects like images, video, Java or OLE objects.

The current trend observed on the WWW is to define a way for extending this model to support more data or live objects [Berners 95]while nothing is done to define how the text model could be extended.

There is no doubt that the large success of the WWW came from the sudden availability of a great amount of world-wide searchable textual information. This search ability was made possible because the information was expressed in a public non-opaque non-binary text format: HTML.

While it is without any doubt necessary to enable the WWW to handle more and more data or live objects, these are often expressed in a non-public or binary format. The proliferation of this kind of data, minimizing, slowly but surely, textual data expressed in HTML could, in the long term, jeapordize the searchable exploitable working scheme based on textual formats which has proved the success of the WWW.
1.1 Tag Proliferation

HTML suffers from its lack of extensibility, and anarchical tag proliferation is in danger of breaking the WWW. A lot of the recent tag proliferation came from the need to offer improved presentation and layout of online documents. It is obvious that HTML, in that area, is far from the sophisticated layout formats which exists in pre-press software such as Adobe PageMaker or Quark XPress.

The purpose of associating improved presentation, or at least adding some flexibility to the current HTML scheme is, in our view, addressed by the associating of style sheets to the HTML tags, and the work of the W3C in that direction (CSS [Lie 95], DSSSL[Bozak 95]) is a solution which should be adopted.
1.2 Semantic tags

Another reason for tag proliferation has been the need to express and use more complex structured information than is found in the HTML structure model.

Documentary data are more clearly identified by semantic tags [Paoli 94]. Semantic tags are used to precisely identify corporate or industry specific information such as motors, product parts, transistors, or other objects which require a very precise description. This is one of the strong points of SGML and there is always a need for mission-critical data to be formalized and stored using such markup.

It is in specialized corporate contexts that we see the greatest need for such markup. It is generally accepted that people in this kind of corporate environment often manipulate the same kind of structured information which describes very precisely the nature of their business or technical data. In the case of an electronic components manufacturer, for example, it would not be uncommon for engineers to work together on the definition of a new electronic device and on the documentary data which could best describe it.

We started off at the base at Nieuwezijds Kolk 29, which is close to Centraal Station. After being fitted for our bikes, and hearing a talk about the route, the brakes, and security, we set off. We rode behind Centraal Station and crossed the river on the ferry. After that we had a long ride down a quiet canal, and it was really pretty. It had a very rural feel to it despite being just a short distance from Amsterdam. We stopped at a windmill further down, and then continued riding. We frequently stopped to hear our guide tell us about the area.

We stopped at a pretty village called Broek in Waterlaand for lunch at a pancake house, which was wonderful. This is not included in the price of the tour – allow around 10 euros. Both sweet and savoury pancakes were on the menu, plus sandwiches etc. We then had the easiest part of the day, riding across farmland.

We later appraoched another small village, where the riding got harder due to the heavy traffic on the road, and we stopped for a drink. There were some good views of Amsterdam. We then returned to Amsterdam via a different route. We were congratulated by the leader and then left to deal with our aching bones and legs.

I enjoyed the day mostly, but I am not a confident cyclist and I get very nervous about traffic coming too close to me. That was worrying. The leader was good, very patient and reassuring. The other group members were a good mix of internationals. One couple complained about everything, but the rest of the group was nice. There was a wide mix of ages, from late teens to early retired people. The tour was conducted in English. I went on my own, but soon felt part of the group. The whole day, for 6 hours, cost 22.50 euros including bike rental. You could rent the bike and do the same route for a lot cheaper, but I didn’t want to do it alone. The same company also rent bikes and do a biking tour of the city of Amsterdam.

Tagging in the real, meatspace world is an urban, semi-artistic endeavor which entails scrawling your handle all over public surfaces. Tagging in the wired universe is, of course, a folksonomy, a means of categorizing and organizing ideas, terms, things and themes. Semapedia brings the two together again, so to speak. Here’s how it works: you choose a wiki article with a real world connection. Copy the article’s URL and paste it into the Semapedia
form (on the site’s homepage). Semapedia will churn out custom made tags available as a printable PDF. Print out the tags and attach them according to the content they link to (in some cases, it’d be wise to ask for permission, or simply do your deed at under the cover of nightfall). Cell phone users will be able access the wiki info by simply pointing their screens at the tag (provided they first download a 2D Barcode Reader for their phone). It’s tagging 2.0 style.

In their own words;

“Our goal is to connect the virtual and physical world by bringing the right information from the internet to the relevant place in physical space. To accomplish this, we invite you to create Semapedia-Tags which are in fact cellphone-readable physical hyperlinks.”
