Format Logic

This document describes the logic that Pika uses to determine various formats for display.

Table of Contents

Basic Information and Process

When building format facet logic, Pika references a combination of information from the MARC record. We reference location codes, i-types, and material types. Formats can be determined by material type, location type, collection code, i-Types, etc. At Marmot we cannot use these alone, because they are either not discreet enough, or they conflict. 

The process for format determination always starts by examining the MARC Leader to determine whether or not the leader position 6 is J for an initial determination of MusicRecording. After this determination, Pika will reference mapping based on other fields in the MARC, as described below. Typically, information in the leader field is used for format determination as a last option. When using the MARC leader, characters are counted using MARC record position counting that is similar to program position counting. Similarly, the 007 is the second to last option for format determination and is only applied if format determination cannot be referenced from any other MARC fields.
