Martin Desruisseaux commented on SIS-81:
----------------------------------------
Re-open as a side-effect of the work in {{MetadataVisitor}}. We may not provide
an {{APPENDABLE}} enumeration, but another enumeration that may be useful could
be {{STAGED}}. That annotation would be set by the user and treated in the same
way than {{EDITABLE}}, except that setting a metadata to that state
automatically set all children to that state too (if they are not {{FINAL}}),
and modifying a staged metadata automatically put it back in {{EDITABLE}} mode.
The intent is for allowing users to mark which metadata are ready for
publication, pending a last review.
Note: we will probably not do that for SIS 1.0. For now, we will put only
{{EDITABLE}} and {{FINAL}} enumeration values. But we use this JIRA task for
recording ideas like {{STAGED}}.
> Replace ModifiableMetadata.isModifiable() by an enum

> Key: SIS-81
> URL: https://issues.apache.org/jira/browse/SIS-81
> Project: Spatial Information Systems
> Issue Type: Improvement
> Components: Metadata
> Affects Versions: 0.3, 0.4, 0.5, 0.6, 0.7, 0.8
> Reporter: Martin Desruisseaux
> Assignee: Martin Desruisseaux
> Priority: Major
> Fix For: 1.0
>
>
> The {{ModifiableMetadata}} abstract class provides a {{isModifiable()}}
> method which currently returns a {{boolean}} value. The boolean value should
> be replaced by an enumeration containing the following values (for now):
> * {{EDITABLE}}
> * {{APPENDABLE}}
> * {{FINAL}}
> The new functionality is the {{APPENDABLE}} value, which would be like
> {{EDITABLE}} except that only new values could be set; an exception would be
> thrown on attempt to modify an existing value.
