Schema library

The metadata that our members register with us is stored as XML, and our XML schema provides a structure and set of rules to keep everything consistent and interoperable.

If you’re sending us XML directly, it’s important that you understand the schema. If you’re using one of our helper tools, you don’t need to worry too much about the schema as the tool you use will transform your information into XML for you.

As a registration agency of the International DOI Foundation, we follow the ISO/IEC 11179 Metadata Registry (MDR) standard, which specifies a schema for recording both the meaning and technical structure of the data for unambiguous usage by humans and computers.

We have a single deposit schema, which supports a range of different content types (see full list of content types).

We support several versions of the schema but we recommend using the latest version (v5.3.1). For certain updates, we also offer the resource-only section of the schema. (Here’s more information on resource-only deposits).
