Project description

Build Status Documentation Status


This package has been retired in favor of rios.core. Please upgrade ASAP.


PRISMH.CORE is a Python package that provides basic validation and formatting functionality for data structures that adhere to the PRISMH specifications.

Example Usage

This package exposes a handful of simple functions for validating and formatting the standard PRISMH data structures:

>>> from prismh.core import validate_instrument, get_instrument_json

>>> instrument = {"foo": "bar", "id": "urn:my-instrument", "title": "An Instrument Title", "record": [{"id": "field1","type": "text"}], "version": "1.0"}
>>> validate_instrument(instrument)
Traceback (most recent call last):
colander.Invalid: {'': u'Unrecognized keys in mapping: "{\'foo\': \'bar\'}"'}

>>> del instrument['foo']
>>> validate_instrument(instrument)

>>> print get_instrument_json(instrument)
  "id": "urn:my-instrument",
  "version": "1.0",
  "title": "An Instrument Title",
  "record": [
      "id": "field1",
      "type": "text"

For more information on the available functionality, please read the API documentation.
