Ariel J. Lira created DS-1372:
---------------------------------
Summary: Change OAI2.0 DSpaceMetadataExistsFilter to check for one
or more fields
Key: DS-1372
URL: https://jira.duraspace.org/browse/DS-1372
Project: DSpace
Issue Type: Improvement
Components: OAI-PMH
Affects Versions: 3.0
Reporter: Ariel J. Lira
Attachments: DSpaceMetadataExistsFilter.java,
DSpaceMetadataExistsFilter.patch
Class org.dspace.xoai.filter.DSpaceMetadataExistsFilter accepts or rejects
items based on the existence of a single field among its metadata (indicated as
an argument). While for most cases this is sufficient, in other cases it
becomes necessary to check for the existence of at least one of many fields.
As an example, in sedici.unlp.edu.ar, we have 2 metadata fields for
authors:"sedici.creator.corporate" and "sedici.creator.person", so in order to
filter out all items without authors, we should accept only items with either
or both metadata fields.
In OAI2.0 configuration syntax:
<Filter id="authorexistsFilter">
<Class>org.dspace.xoai.filter.DSpaceMetadataExistsFilter</Class>
<Parameter key="fields">
<Value>sedici.creator.person</Value>
<Value>sedici.creator.corporate</Value>
</Parameter>
</Filter>
I attach a plain diff file (aginst git head) and the full .java file.
