HXL core schemas

Schemas describing the core HXL hashtags and attributes. Starting with version 1.1, the standards documentation listing HXL hashtags and attributes at hxlstandard.org is generated directly from this dataset.

See the documentation on the HXL schema format , and the HXL Proxy validation service. Note that this is just a generic default schema—you can also create your own, project-specific HXL schemas.
