TopBraid EDG v7.1.2 - SPARQLMotion webservice throws 404 error

[deviredd...@gmail.com]

Hello,

             Recently we upgraded our TopBraid Enterprise Data Governance(EDG) instance to v7.1.2 (20211227-1946) from v7.0.3. After that our SPARQLMotion script web service calls throw 404 error. Since till v7.0.3 our SPARQLMotion script was available to access as web service but not in v7.1.2 so, is there any change made to SPARQLMotion script feature in v7.1.2?

Below is an example project, which contains a simple SPARQLMotion script. This script is accessible as Web Service in EDG v7.0.3 but not in v7.1.2. I tried looking at the TopBraid Server Administration -> Available Web Services page in v7.1.2 but  SPARQLMotion web service is not listed there.

Thanks,

Hi Sanjeev,

see the 7.1 release notes

    https://www.topquadrant.com/wp-content/uploads/2021/12/TopBraid-Suite-7.1.0-Change-Log.pdf

the SPARQLMotion servlet has been removed. However, most of SPARQLMotion's capabilities remain available when called via SWP scripts. In your example, you can define a simple ui:Service that would have something like <sml:CopyFile ... /> as its ui:prototype and call that using the tbl/swp servlet. Basically it's another syntax for the same building blocks.

While SPARQLMotion was designed as a pipeline language with a graph notation, SWP uses a textual HTML-like representation. The new JavaScript/ADS features also seem to attract more users than our in-house SPARQLMotion technology. Over time we have learned that very few people continue to use the graphical SM notation and we cannot keep all features alive at similar quality forever.

Please feel free to follow-up with specific questions on how to migrate, e.g. via TSM support tickets.

Holger
