Re: [topbraid-users] SPARQL Web Pages without Topbraid Live

Thanks Irene.  The good news is that is pretty much the summary I have
given my client.  The fact that they want a perfect world with powerful,
flexible vendor solutions/tools without vendor-specific
optimization/differentiability is, I suspect, an ongoing discussion not
unique to TQ tools.

 Hi Charlie,



 TBC-ME is a companion IDE (Integrated Development environment) for
 TopBraid Live server and other TopBraid server products such as TopBraid
 EVN and TopBraid Insight.



 When one develops applications using TBC-ME, one presumably is using
 technologies such as SPIN, SPARQLMotion, SPARQL Web Pages, SWP Application
 Component Library and/or Teamworks Framework. Technical features and
 advantages for each of these are explained on their web pages in a fairly
 detailed way. Each page has a tab entitled “Why X” and we would also be
 happy to answer additional questions:



 http://www.topquadrant.com/technology/sparql-rules-spin/

 http://www.topquadrant.com/technology/sparqlmotion/

 http://www.topquadrant.com/technology/sparql-web-pages-swp/

 http://www.topquadrant.com/technology/swa-sparql-web-applications/

 http://www.topquadrant.com/technology/topbraid-teamworks-framework/



 These technologies make it easier to create powerful semantic web and
 linked data applications. If one didn’t use them, then one would presumably
 have to write some not dissimilar code themselves for their applications to
 take advantage of the capabilities. Then, the applications would be
 ‘locked’ to that code.



 In other words, like anything, this is a buy versus build decision. Does
 the organization want to write and maintain their own
 infrastructure/middleware type of code or does it prefer to license it from
 a software vendor? Many organizations these days chose the latter because
 it saves them time, money and reduces risk, but some chose the former.



 Regards,



 Irene

 I have exactly the same issue on my current project with a large provider
 of medical information in Europe.  They can see the utility of developing
 applications in TBC-ME but would like to deploy them on commodity
 technology.  I would appreciate any justifications -- and the more
 technical the better -- for reasons to lock applications to TBL (realizing
 that one is probably execution of SPIN constructs.)



 Thanks in advance --

 Holger,

 Could I get your email so we could discuss off line.

 The main issue is sponsors are consistently asking for open source
 enterprise level solutions, fiscally conservative climate and all.  We try
 to explain the difficulties involved with non-commercial enterprise
 solutions, but shouting into the wind.

Re: [topbraid-users] SPARQL Web Pages without Topbraid Live

2014-07-13 Thread Gregg O'Marr
Charles, 

I preformed a cost comparison/analysis with TopQuadrant's products as one of 
the sets of solutions. One of the pros with the TopQuadrant suite is that you 
actually purchase and own the software after the term of your license, just 
without version updates after your maintenence period expires.  Some other 
commercial solutions you lease their software. Once license term expires so 
does your ability to use it.

I found, overall, the TopQuadrant suite may have a larger initial buy in, but 
the recurring maintenance costs over time lead them to be the more cost 
effective solution.

But as I said previously, sponsors now seem to have the open source phrase 
firm planted in their mind.  Not realizing that that solution requires a 
technology stack to be developed and integrated.  Nor that open source 
solutions do not come with enterprise techsupport support anywhere near what a 
commercial product has. Not to mention the testing a commercial product has 
been put through.

I found that higher ups (decision makers) have extended their home finance 
thinking to program budgets, as in what is my monthly cost and do not ask the 
right question what will be the total cost in the end.

Re: [topbraid-users] Error in swa.AutoComplete

It looks like my keyboard changed my entry as I was typing. All of the 
rdfs:label entries in this repository are xsd:string. And these 
repositories are not mine to change anyway.

  According to the spec (which Jena implements), rdfs:Literal values cannot

 This has no disadvantages and is hopefully a one-time global replace that 
 can be done with a SPARQL UPDATE.

 For the auto-complete index to work, it needs to have xsd:string values

[topbraid-users] faceted search on classes rather than instances?

2014-07-13 Thread Jack Hodges
Can I build a faceted search on classes rather than on class instances? If 
I have a repository that is basically a taxonomy and has all of the content 
at the class level, then faceted search on the classes would provide the 
same benefit as faceted search on instances.

Yes that should work. Classes are just instances - of owl:Class.

So where does the rdfs:Literal come from then? It must be stored
