This documentation explains the features and the usage of the importer framework.
Enabling the framework can be achieved by uncommenting the following step in item-submission.xml
.
Implementation specific or additional configuration can be found in their related documentation, if any.
Please refer to subdivisions of this documentation for specific implementations of the framework.

Features
- lookup publications from remote sources
- Support for multiple implementations
...
The importer framework does not enforce a specific input format. Each importer implementation defines which input format it expects from a remote source. The import framework uses generics to achieve this. Each importer implementation will have a type set of the record type it receives from the remote source's response. This type set will also be used by the framework to use the correct MetadataFieldMapping for a certain implementation. Read Implementation of an import source for more information and how to enable the framework.
Transformation to DSpace item
...
Then create a spring configuration file in [dspace.dir]/config/spring/api
.
Each DSpace metadata field that will be used for the mapping must first be configured as a spring bean of classorg.dspace.importer.external.metadatamapping.MetadataFieldConfig.

Note that the single field mappings used for the combined author mapping are not added to this list.
Framework Sources Implementations
PubMed Integration
Introduction
First read the base documentation on external importing This documentation explains the implementation of the importer framework using PubMed (http://www.ncbi.nlm.nih.gov/pubmed) as an example.
The configuration done for pubmed specifically is located at pubmed-integration.xml in dspace/config/spring/api I will not go into detail to what exactly is configured for the pubmed integration as it is simply a usage of the classes explained here
Additional ConfigEnabling PubMed Lookup (XMLUI Only)
[dspace.dir]/config/item-submission.xml.
Uncommenting this step will permit the user to do the PubMed based lookups during their submission.

<!-- Find publications based on ID/DOI/Title/Author to pre-fill the submission. XMLUI ONLY.
For JSPUI version, see JSPUIStartSubmissionLookupStep under <step-definitions> above.

After uncommenting hat step, simply restart your servlet container, and this lookup step will be available within your deposit process.
Publication Lookup URL
To be able to do the lookup for our configured import-service, we need to be able to know what
URL to use to check for publications.
This URL the publication-lookup.url
setting defined within the [dspace.dir]/config/modules/publication-lookup.cfg
. You may choose to modify this setting or override it within your local.cfg.
This setting can be modified in one of two ways:
- You can choose to specific a single, specific URL. This will tell the lookup service to only use one location to lookup publication information. Valid URLs are any that are defined as a
baseAddress
for beans within the[src]/dspace-api/src/main/resources/spring/spring-dspace-addon-import-services.xml
- Spring config file.
- For example, this setting will ONLY use PubMed for lookups:
publication-lookup.url=http://eutils.ncbi.nlm.nih.gov/entrez/eutils/
- For example, this setting will ONLY use PubMed for lookups:
- By default,
publication-lookup.url
is set to an asterisk ('*'). This default value will attempt to lookup the publication using ALL configured importServices in the[src]/dspace-api/src/main/resources/spring/spring-dspace-addon-import-services.xml
Spring config file
PubMed Metadata Mapping
The PubMed metadata mappings are defined in the [dspace.dir]/config/spring/api/pubmed-integration.xml
Spring configuration file. These metadata mappings can be tweaked as desired. The format of this file is described in the "Metadata mapping" section above
PubMed
specific classes Config
These classes are simply implementations based of the base classes defined in importer/external. They add characteristic
behavior for services/mapping for the
PubMed specific data.
Metadata mapping classes
- "PubmedFieldMapping". An implementation of AbstractMetadataFieldMapping, linking to the bean that serves as the entry point of other metadata mapping
- "PubmedDateMetadatumContributor"/"PubmedLanguageMetadatumContributor". Pubmed specific implementations of the "MetadataContributor" interface
