An XSLT implementation of the Metaschema toolchain for generating schemas, converters, and model documentation.
Typically any of these operations will combine several lower-level operations in a defined sequence.
More details (produced by surveying the files) can be seen in file-manifest.md. Note however that this file is not reliable if it is not more recent than the files described.
In addition to this readme, this folder contains XSLT transformations (*.xsl), and XProc pipelines (xpl). The XSLT provides stable runtimes to the supported operations as described below. The XProc provides optimized runtimes when producing multiple outputs (results) from single inputs.
See each subdirectory README for more instructions.
XSLT and logic used as common modules by other utilities.
Moving or removing this directory will often break things.
Implements a metaschema composition pipeline - producing a unified single metaschema from a metaschema top-level module, by performing imports and linking references.
This subroutine is a dependency for most other metaschema processes, so like common this directory should be kept in place.
Logic to generate converter transformations (XSLT) capable of producing JSON from XML or XML from JSON, according to mappings defined by appropriate metaschema definitions, defining schemas to which the respective data sets are valid.
Logic to create HTML-based web-ready documentation of XML and JSON schemas based on a metaschema.
Provides support for parsing and mapping Metapath, the metaschema path language.
This directory is a dependency for logic in converter generation, which uses it to match JSON in conversion into XML, and schema generation, which uses it to implement path traversal in constraints definition and implementation.
Logic to provide schemas for validating XML or JSON according to definitions provided in a metaschema.
Generators for XSD and JSON Schema v7 are provided.
Additionally, a partial implementation of Metaschema constraints via a Schematron cast is offered, as a basis for future work.
Some testing artifacts.
Also find testing within each subdirectory, appropriate to its functionalities.
Miscellaneous utilities. Due for cleanup.
Provides support for extra-schema validation of Metaschema instances against constraints implicit in Metaschema semantics.
Note that validation provided here via Schematron applies additionally to regular structural schema validation of a metaschema, using its XSD.
