Versioning for configurations of reusable artifacts

A system comprising:

• a processor programmed to initiate executable operations comprising:
• creating an artifact baseline corresponding to a present version of a first artifact;
• responsive to creating the artifact baseline making the present version of the first artifact, and present versions of children artifacts of the present version of the first artifact, immutable;
• and
• responsive to identifying a change to the present version of the first artifact, automatically creating a new version of the first artifact, wherein the new version of the first artifact is mutable.

A computer program product for versioning configurations of reusable artifacts, the computer program product comprising a computer readable storage medium having program code stored thereon, the program code executable by a processor to perform a method comprising:

• creating, by the processor, an artifact baseline corresponding to a present version of a first artifact;
• responsive to creating the artifact baseline, by the processor, making the present version of the first artifact, and present versions of children artifacts of the present version of the first artifact, immutable;
• and
• responsive to identifying a change to the present version of the first artifact, automatically creating, by the processor, a new version of the first artifact, wherein the new version of the first artifact is mutable.

A method of versioning configurations of reusable artifacts, the method comprising:

• creating an artifact baseline corresponding to a present version of a first artifact;
• responsive to creating the artifact baseline, by a processor, making the present version of the first artifact, and present versions of children artifacts of the present version of the first artifact, immutable;
• and
• responsive to identifying a change to the present version of the first artifact, automatically creating a new version of the first artifact, wherein the new version of the first artifact is mutable.
