I am happy to announce that RELAX SEO Services have been released some applications using tags and SCOT(not officially, but you can test them).

Two examples are currently online: http://relaxseo.com/relax-seo-front-page.php and http://relaxseo.com/ac-module-y.php

David Hambly said:

I would characterize our work as a demonstration of the separation between the display (lens) and the source (content). Everything goes through the engine which is RDF aware. It is not a faceted browser but it could be. At present, it does not consult a triples store … but it could.

As an endpoint, it may represent a cloud of relevant links (Knowledge Domains) rendered as a scot ontology (prefered).

The objective shall provide a dynamic representation of knowledge contained within a web site and relationship with other entities (RDF or non-RDF) … as a compliment to dynamic content such as Exhibit, Dapper etc. We care as much about non-RDF as we do RDF and intend to ‘flatten’ wherever possible.

Also you can find more details in here and The Semantic Web comes of age.

I’ve talked with David Hambly from the initial stage of the SCOT project. He gave me great feedback. Thanks, David.
I think we can find out more useful cases from RELAX SEO sooner or later.

We have changed many part of the SCOT ontology. As we mentioned before, SCOT has connected Tag Ontology to describe a tagging activity and links sioc:Item directly using scot:tag_of property.

We will summarize the changes when we release the spec officially. Since this is a draft version for SCOT, some additional changes will happen.

Please feel free to give us any comments and feedbacks.

Update

Alexandre Passant gives three comments

• Cardinality issue for tag label: should consider how to apply
• tag name: scot:tag_label is subproperty of tags:name
• scot:created_by: this property is subproperty of foaf:maker

Richard Cyganiak points out that scot:created_by property is confused with scot:has_usergroup. As Alex suggests this property is subproperty of foaf:maker. It might be clear. And he also points out the usefulness of inverse properties. John Breslin already mentioned it.

We are happy to announce that now SCOT has a logo.
When we launched this project, we introduced the folksonomy triangle consisting of a user, a tag, a resource.

Basically, SCOT aims to represent folksonomies beyond individual tagging covered these three components.
The logos illustrates this perspective. Each triangle in the logo means individual taging and each triangle can be connected each other.

John, Sungkwon and I have talked many times to improve SCOT ontology. There are several tag ontologies such as Tag Ontology, MOAT, and even Gruber’s Conceptual Model.

We need to provide a method for interlinking among the existing tag ontologies and also to consider overall pictures for linking among existing RDF vocabularies such as SIOC, FOAF, SKOS, etc. Although we didn’t finish this work at this moment, we would like to give some idea for discussion.

1. Relationship between Tag Ontology and SCOT

Currently, we don’t provide a method to describe individual tagging activity consisted of a user, tags, a resource, and date. The Tag ontology already supports it. So it would be better to use the classes and properties of Tag Ontology. The change is that scot:Tagcloud connects to tags:Tagging class with scot:taggingActivity and also scot:Tag is subclass of tags:Tag.

2. We will change two properties scot:taggedItem (subproperty of tags:taggedResource and scot:tagUsed (subproperty of tags:associatedTag).

3. The following picture illustrates simplified view of SCOT vocabularies.

4. We will change the properties associated with scot:Tagcloud and scot:Tag.

SCOT used in the OpenLink system. More details see New Features in OpenLink Data Spaces.

@From Kingsley’s comment. It’s so good example to use SCOT and other RDF vocabularies. See OpenLink RDF Browser:
