Methods and systems use a standard schema to describe the capabilities of a peripheral device, such as a printer device, in a structured and easily discoverable way. The schema can allow different peripheral device implementations to describe their capabilities in a consistent way to those entities that might query for the capabilities. The schema syntax can allow for direct querying of individual values, as well as for querying whole sections of the schema so that an accurate and complete understanding of the device can be gleaned.
