Changes Adopted for WCIA Schema​

Version 1.2.0 (Implementation Date: 2022-01-21)​

  • document_schema_version

    • Effected Schema: Transfer Data Schema, and Lab Result Schema

    • Notes: this drops the 4th version digit.

  • sample_source_id

    • Effected Schema: Lab Result Schema
    • This field was a v1.1 addition to the WCIA Transfer Data Schema.
    • This field will now be returned within the sample object of the WCIA Lab Result Schema.

  • lab_result_link

    • Effected Schema: Transfer Data Schema
    • This field is an existing property of an inventory transfer item object.
    • This field is defined as a URL string pointing to the WCIA Lab Result Link for that item.

  • All keys in both schema are lower case.

    • The upper case letters were the result of the Document’s auto-correct feature.

  • Laboratory Details

    • Add laboratory details to the Lab Result schema
