Re: [topbraid-users] Using Top Braid Composer/Ensemble with other web apps and Conceptual issues

2012-01-05 Thread Bob DuCharme
Bruce, Semantic MediaWiki uses MySQL, but not as a triplestore per se (i.e. with the Jena SDB interface), so the only way for TopBraid to use that data directly would be with the D2RQ interface, and then you'd have to figure out how the system models triples in MySQL. http://semantic-mediawiki.org

Patrick, Derek; It's also vitally important to let us know what version and edition of Composer is being used, as well as the OS. For example, Unix-based systems often default to Open JDK, but Sun/Oracle JDK is required for Composer (see http://www.topquadrant.com/products/supportedPlatforms3.5.

Hello Jeff; Note that if you save the password in the mapping file, the password is saved in plain text. That won't pass many organizational security requirements. You should not have to re-enter the password each time as the password will be saved in secure storage. The next time you open the

Just a follow up to this, as I spent some time on this same issue this morning. I'm confused as to why the wizard doesn't store the password in the Mapping model, thus requiring you to re-enter the password yourself the next time you go to open the D2RQ database, which isn't an entirely obvious

Indeed Holger this is cleaner. But there is also the user's perspective who doesn't always want separate properties for several potential datatypes, certainly when the datatypes are very close to each other such as xsd:date, xsd:gYearMonth, xsd:Year. In a real project in the Cultural Heritage doma

Aza, I think I know where you are getting at, because I remember I faced a similar issue earlier, which I fixed. After you download and unzip/install TopBraid Composer, when you start it up for the very first time, Eclipse or TopBraid Composer registers some UI components and configuration i
