Convert xsd schema to json schema to generate forms to edit xml metadata

We believe that

There are available libraries to translate xsd schemas to json schemas that can then be used to produce valid XML metadata. This way we can use our jsonschema based component to edit XML metadata.

To verify that we will

• Try to convert data cite schema into json schema using available online converters.
• Download datacite schema standard using available node libraries.
• Convert the XML standard into a JSON schema using available libraries:
  • xsd2jsonschema
• Use this json schema to generate the form in HARDOCS
• Store the json and then convert it to XML in the project

And measure

• How simple it is to injest

  We are right if

• XSD to JSON schema is 100% compatible or almost compatible

We observed

• XSD and JSON schemas are not100% compatible which might require manual adjustment of the son schema to make it 100% compatible.
• Converted Datacite XML to JSON schema is not current loaded in the form and is not throwing an error
• Subschemas need to be also accessed or downloaded, because current online converters and libraries do not compile such schemas. We found a ndoe library called cxsd that fetches all the subschemas and organizes the files in a very useful way.

There are potential solutions:

From that we learned that

• The most clean and secure solution is to generate a form from xsd instead of from json schema as another hardocs component
• xml2html2xml generates a form and XML in vanilla javascript

Therefore, we will

• We will try solutions that converts xsd schemas into forms like this one: xml2html2xml
• We will explore if we can replicate the json schema form generator with schemas.
