Bruce, < It would be interesting to be able to use xsl to convert the rdf file for html output so that people could see and browse different profiles.>
I wanted to add a little to what Irene said: because RDF/XML gives you multiple ways to represent the same triple, using XSLT to find a given piece of information (for example, the rdfs:label value of resource <http://foo/bar>) can make for a very messy stylesheet. Two better ways of doing this are: - Do a SPARQL query for the data you want, and write an XSLT stylesheet to process the SPARQL Query Results XML format (http://www.w3.org/TR/2008/REC-rdf-sparql-XMLres-20080115/) that gets returned, because this format is much simpler and more regular than RDF/XML. When viewing query results in TBC Free, you can do a Save As to create this XML version. TBC Maestro Edition and TopBraid Live can function as SPARQL endpoints so that this process can be more automated. See http://topquadrantblog.blogspot.com/search/label/SPARQL%20endpoint for more on this. - With TBC Maestro Edition and TB Live, you can also take advantage of SPARQL Web Pages, which let you generate HTML (and XML) by embedding SPARQL queries in HTML or XML template documents. I wrote a very basic introduction at http://topquadrantblog.blogspot.com/2010/11/getting-started-with-sparql-web- pages.html and it points to other resources that show more about the full power of this technique. Trying to build full applications around the free edition will only take you so far. If you take a look at the Application Development Quickstart Guide at http://www.topquadrant.com/docs/tbc/AppDevQuickstartGuide.pdf, you'll get an idea of some of the things you can do to build web services and interactive applications for end users with TBC Maestro Edition that can then be deployed to TopBraid Live.

Every RDF resource has a type. Types are classes. When you select a resource that is used as a type, you see in the Instances view resources that are members of this class. Resource you selected shows up in a form that can be edited. Resources whose type is Class and Property are special in that they have views of their own where they are shown in a hierarchical tree using rdfs:subClassOf and rdfs:subPropertyOf to build the hierarchy. Even if you are not creating new classes and properties, these views are still useful for you to understand the ontologies (data schemas) you are using and to navigate through the data that is organized based on these schemas. With that in mind, everything in the Getting Started Guide with the exception of working with OWL restrictions is teaching some skill I believe to be relevant to what you are working on. Especially, sections about organizing the workspace, imports, working with multiple graphs, SPARQL, etc. There is a number of ways you can organize your project. One approach that may work for you would be to name the project personalprofiles.fwwebdev.com. Then create a folder for each foaf file you are planning to create e.g., BruceWhealton folder, JeanArthurJones folder, etc. Then, when you right click on a folder (e.g., BruceWhealton) to create new, http://personalprofiles.fwwebdev.com/BruceWhealton/unnamed0 will already be filled out for you. You will just need to replace unnamed0 with foaf. With this approach you can keep multiple files called foaf.rdf in one project. Of course, relying on uniqueness of a name is not particularly robust or scalable. The idea of having foaf files is that each person would create their own. So, the granularity is per person and the URIs end up being different because each person will put his file at whatever web domain they are hosting. In a Genealogy application you are describing, you would most likely use an RDF database rather than many files. You could still, of course, keep information about each person as an individual named graph, but the graphs ids may be based on some identifier that is more unique than a name. < I did notice that the second file when I created that, did not have the same imports or all the imports that the first one did.> This is really up to you. Each graph you create will have whatever imports you specify. < It would be interesting to be able to use xsl to convert the rdf file for html output so that people could see and browse different profiles.> HTML presentation is already part of TopBraid. When you select a resource you can click on the Browser tab in the form to see information about the resource presented in HTML. For viewing outside of TopBraid, yes, you could create XSLT that is specific to your data and your presentation requirements.

I want to move to doing a Genealogy application for a client. We can use the name spaces foaf, bio and rel, as well as geo, and some others. For practice I wanted to be able to learn this by looking at a foaf.rdf file that I created by hand and try to do it using TBC. Then I can get all the foaf files created in TBC. So, the challenge was with the regard to the above, and with your explanation, I would create the resource that is equal to my blog's URL. Then I want to say that the resource has a dc:title. I think the difficulty is that I am looking at the documentation and I keep finding information about creating ontologies. I'm at the point of using an ontology or several to create a triple store in rdf, or in this case, specifically a foaf file. This is another related issue. I thought I got an error when I tried to work with more than one file in a project but that doesn't make sense. Maybe one should only have one file in a project open at one time. I was using this naming convention when creating files, which seems to be ok: http://personalprofiles.fwwebdev.com/BruceWhealton/foaf.rdf and http://personalprofiles.fwwebdev.com/JeanArthurJones/foaf.rdf I did notice that the second file when I created that, did not have the same imports or all the imports that the first one did. For a large community it wouldn't make sense to put everyone in one foaf file. Someone on this board said the same thing. It would be interesting to be able to use xsl to convert the rdf file for html output so that people could see and browse different profiles. So, for now, I'm looking at expanded foaf files that include other ontologies. I will also do this for all my web development clients so that they can contribute to the Semantic Web and as part of my training that I am pursuing.
