The following Core Services can be used to select the evaluation services to apply during an evaluation epoch. Details on each are provided at DataFAQs Core Services.
- select-datasets/identity
- select-datasets/via-sparql-query

This page describes how to write an epoch configuration, which specifies evaluation services to apply and [datasets to analyze](Selecting the datasets to analyze). Here, we focus on selecting the evaluation services.
An epoch configuration prescribes the process to use to select evaluation services and datasets for an evaluation epoch. The configuration is described using RDF using the PROV-O vocabulary, among others. All FAqT Service Selectors follow the same simple pattern. First, they accept an RDF graph via HTTP post. Next, they return an RDF description of the FAqT Services to use in the evaluation epoch. The structure of the RDF that goes to each FAqT Service Selector can vary depending on what it does, but all of their output is structured in the exact same way.
