Just as with bitcoin, you can store general purpose data in a MultiChain blockchain using "OP_RETURN" outputs. Our libraries for doing this with bitcoin can also be used with MultiChain:

MultiChain alpha 7, released today, provides a new easy API for doing this, called appendrawmetadata. It can be used after createrawtransaction and before signrawtransaction and sendrawtransaction.
