It serves as the basic [[data model]] in numerous projects of the Stanford University Database Group, including Tsimmis, Lore, and C3. <ref name=":0">{{Cite web|url=http://infolab.stanford.edu/~mchughj/oemsyntax/oemsyntax.html|title=A Standard Textual Interchange Format for the Object Exchange Model (OEM)|website=infolab.stanford.edu|access-date=2020-02-07}}</ref><br />

Slight variations of OEM have evolved across different Stanford projects. In Lore, labels are actually on parent-child "links" rather than objects. For example, if an OEM object has multiple parents, different parent objects may use different labels to identify that object. An atomic value encoding a person's name might be included in one complex object using the label "Author" and in another complex object using the label "Editor." In C3, additional attributes are required for each object to annotate the changes to the object that have occurred over time. <ref name=":0" /><br />
