Assumptions

refscan was designed under some assumptions about the schema and database, including:

1. Each source document (i.e. document containing references) has a field named type, whose value (a string) is the class_uri of the schema class of which the document represents an instance. For example, the type field of each document in the study_set collection has the value "nmdc:Study".

Development status

refscan is in early development and its author does not recommend anyone use it for anything without reviewing its code first.

Tips

refscan requires the user to specify the path to a schema in YAML format. If you have curl installed, you can download a YAML file from GitHub by running the following command (after replacing the {...} placeholders and customizing the path):

# Download the raw content of https://github.com/{user_or_org}/{repo}/blob/{branch}/path/to/schema.yaml
curl -o schema.yaml https://raw.githubusercontent.com/{user_or_org}/{repo}/{branch}/path/to/schema.yaml

For example:

# Download the raw content of https://github.com/microbiomedata/berkeley-schema-fy24/blob/main/nmdc_schema/nmdc_materialized_patterns.yaml
curl -o schema.yaml https://raw.githubusercontent.com/microbiomedata/berkeley-schema-fy24/main/nmdc_schema/nmdc_materialized_patterns.yaml
