1. A method for metadata processing in a computer system, the method comprising acts of:
receiving application data and associated first metadata, wherein the computer system includes a host processor configured to use the application data;
identifying one or more first policies according to which the first metadata was created;
determining, based at least in part on the one or more first policies identified, whether the first metadata is compatible with one or more second policies being enforced in the computer system; and
in response to determining that the first metadata is not compatible with the one or more second policies being enforced in the computer system, processing the first metadata to obtain second metadata to be associated with the application data for use in enforcing the one or more second policies in the computer system.
