-------------------------------
This seems to be a good improvement Ariel, thanks!
So far it worked fine, however, i'm waiting for others testing results.
> 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
> Assignee: João Melo
> Labels: oai, oai-contexts, oai-filters
> Fix For: 3.0
>
> 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.
