basic-subclass

This example illustrates adding classes and class annotations into an existing SubClass hierarchy.

Constructs illustrated:

• SubClass
• Annotations

The example does not make use of reasoning / automated classification or class expressions.

Instructions:

• Open chromosome-parts.owl

Adding new classes (basic):

• Add the term "replication fork" to the ontology under "chromosomal part"
  • Don't worry about the ID
  • See the file "HINTS.obo" or the existing GO for the exact values
  • Add a text definition
    • Add 2 def dbxrefs to the text definition
  • Add a related synonym
  • Add an dbxref

Synonym properties:

• Add the term "site of double-strand break" to the ontology under "chromosomal part"
  • Follow the same procedure as fore the example above
  • Add a synonym dbxref. E.g. synonym: "site of DSB" EXACT [PMID:21035408]

Moving around classes:

• Add the term "intracellular non-membrane-bounded organelle"
• This should go between chromosome and non-membrane organelle and intracellular organelle part
