Schemas

A StagingSchema represents sets of specific staging instructions. Determining the schema to use for staging is based on primary site, histology and sometimes additional discrimator values. A StagingSchema includes the following information:

• schema identifier (i.e. "prostate")
• algorithm identifier (i.e. "cs")
• algorithm version (i.e. "02.05.50")
• name
• title, subtitle, description and notes
• schema selection criteria
• input definitions describing the data needed for staging
• output definitions describing the data produced from staging
• list of table identifiers involved in the schema
• a list of initial output values set at the start of staging
• a list of mappings which represent the logic used to calculate staging output

To get a list of all schema identifiers,

Set<String> schemaIds = staging.getSchemaIds();

To get a single schema by identifer,

StagingSchema schema = staging.getSchema("prostate");

Internal structure

The schemas are represented internally by JSON files (which are the same JSON files that SEER*API provides). For example, here are all the schemas used for algorithm "cs" and version "02.05.50"
