GSA changes tack on solicitation. Again

FCW reports that GSA issued another modification to its solicitation for the data and system to power by January 1st; now they just want data and no software. This is all rather inscrutable to me. From the article:

“GSA … didn’t say why they changed the RFP. GSA did say in its answers that it didn’t want groomed software, only groomed data that will run in the government’s software.”

So what’s this software that the government has? Where’s it come from? Could it possibly be the system that GCE (who supports FPDS-NG) released yesterday?
