The new creation and use of entitlement constraint templates methods and systems can be linked to software offerings in a software catalog. Allowing software catalog experts to link contractual entitlement data with software product offerings via constraint templates on such a varying list of constraint types, establishes a highly robust software catalog knowledge base. The result is significant cost savings in terms of time spent inputting entitlement constraint data by contract analysts as well as minimizing errors by those analysts who would otherwise be required to have a very high level of expertise in the software offerings while potentially inputting the same constraint data repeated times.
