Geospatial Digital Rights Management Open file rept

摘要

Distributors of geospatial data must ensure that agreements made with data providers are adhered to by controlling the access and use of data. Digital Rights Management is a way to ensure that these agreements are honored. Digital Rights Management systems include a framework for implementation and rights policies which are attached to data and describe the rights users have regarding the data. Rights policies are written in rights expression languages, one of which, Open Digital Rights Language, is particularly well suited for digital rights management systems for geospatial data.
