We saw in Chapter 1, Building BizTalk Server 2013 Applications, that schemas are the cornerstone of any BizTalk SOA solution, and they are also the basic building block of a MABS solution for the same reason. The MABS schema editor has a similar development experience to that of the BizTalk server version, and schemas created in BizTalk can be used without modification. Promoted properties on BizTalk schemas are ignored.

MABS uses transforms to transform messages from one structure to another in the same way that BizTalk server solutions use maps. The MABS Transform Editor (TRFM) is very different from the BizTalk map editor, and BizTalk maps cannot be used directly in MABS unless it uses an external XSLT file. BizTalk maps can be converted to transforms with a wizard, but this has some limitations. For example, some functoids may not get converted and are converted to an arithmetic expression functoid in the TRFM map with an empty expression value.
