A crystallography domain ontology based on EMMO and the CIF core dictionary. It is implemented as a formal language.

• Proposal
• accepted, under development
• official

This domain ontology is work-in-progress (WIP), it is in the process of being accepted as a task group by the EMMC.

• Application submitted: 15 June 2020
• Application accepted on: TBD

This ontology builds on top of EMMO. See the following table for version compatibilies:

The Crystallography Domain Ontology can be access or opened in Protege using the following url

https://raw.githubusercontent.com/emmo-repo/domain-crystallography/master/crystallography.ttl

It can also be cloned from its GitHub repository. With ssh access to GitHub set up, the Crystallography Domain Ontology can be cloned with

git clone git@github.com:emmo-repo/domain-crystallography.git

In EMMO-python correct import is obatined with

from emmo import get_ontology

# Loading crystallography from local repository
cryst = get_ontology('/path/to/crystallography.ttl').load()

# Loading crystallography from web
cryst = get_ontology('https://raw.githubusercontent.com/emmo-repo/domain-crystallography/master/crystallography.ttl').load()

The Crystallography Domain Ontology is developed and maintained by the EMMC Crystallography Domain Ontology Task Group within the EMMC Focus Area Interoperability.
