Nested Schema causing validation error

[sreedesai]

Hi Jeff,

Getting an error when validating. It is probably not loading the nested schema files.

Fact NameOfOfficerWithCustodyOfCorporateBooks references a namespace with a URI of http://ferc.gov/form/2020-01-01/ferc, but no schema can be found for that namespace.
Schema element information is not available for this fact.

Schema it is trying to import is in the same folder as the Main schema referencing it.

Thanks for the report! Can you attach the XBRL instance file as well as any schemas or linkbase documents that you have locally? I'd like to be able to reproduce and debug the issue.

Here they are.

fer-20200228-121430.zip

Form1.zip

[JeffFerguson]

Thank you!

[JeffFerguson]

So the fer-20200228-121430 ZIP is the main XBRL instance? Do you have everything in the same folder along with the contents of the other ZIP?

[sreedesai]

Form1.zip is the industry standard taxonomy and fer-20200228-121430.zip is the xbrl sample instance we are trying to validate against it.

[JeffFerguson]

Understood. Thank you. And do you happen to know which version of Gepsio you're using?

[sreedesai]

I am sorry, misread your question. Yes, they are in the same folder.
Library: 'Gepsio' version '2.1.0.16'

[JeffFerguson]

Thank you! I'll start looking at this today.

[JeffFerguson]

Yikes! Gepsio reports 1,827 validation errors on the document you provided. I'm guessing that the number will come down after the fix is applied. Thanks again for the samples. They helped me write a unit test for this issue. I'm debugging the unit test and Gepsio interactions now.

[JeffFerguson]

Yep. Looks like a bug to me. Here is the schema reference chain that I see:

• The schema element for fact NameOfOfficerWithCustodyOfCorporateBooks is defined in ferc-core_2020-01-01.xsd
• fer-20200228-121430.xml is the XBRL instance document
• fer-20200228-121430.xml has a <schemaRef> to ferc-all_2020-01-01.xsd
• ferc-all_2020-01-01.xsd has an <import> of ferc-core_2020-01-01.xsd

I'll debug Gepsio's schema loading processes now.

[JeffFerguson]

As I suspected: Gepsio is not properly handling <import> directives in top-level schemas. I'll get to work on a fix.
