The functionality previously provided by om has been gradually removed from Samvera Gems (with the most recent being the changes introduced into hydra-works in samvera/hydra-works#354). As such, the community has generally shifted away from approaches involving the usage of this Gem to provide an object-oriented API to XML Documents.

Jump In:

A library to help you tame sprawling XML schemas like MODS.

OM allows you to define a "terminology" to ease translation between XML and ruby objects – you can query the xml for Nodes or node values without ever writing a line of XPath.

OM "terms" are ruby symbols you define (in the terminology) that map specific XML content into ruby object attributes.

om is a Core Component of the Samvera community. The documentation for what this means can be found here.

The solrizer gem provides support for indexing XML documents into Solr based on OM Terminologies.
That process is documented in the solrizer README
