Object 'Fixity'
Fixity refers here to whether the objects change once ingested into the repository.
Researchers often want data objects that are continually changed or updated as the
research project progresses. A good example is a record of climate data that grows
each time new values are collected. Such a changing data object is not appropriate if
it is linked to a publication as part of the permanent scholarly record. For this
purpose it is preferable to have a snapshot of the data object or an extracted subset
that will not change post publication.
