This document discusses developing a custom polling importer to ingest and process external content in AEM. It describes adding a new importer scheme for a Jira feed, which returns large XML documents. The implementation involves creating an OSGi bundle with an Importer service that parses the Jira data, applies XSLT transformations, and imports the results.

Jira Query
Result is a 13MB XML document
o Useless elements
o Calculations needed to be applied in parallel

The Importer Scheme
6
Add a custom Scheme
1) Make a Copy of: /libs/cq/ui/widgets/source/widgets/wcm/FeedImporter.js
2) To: /apps/cq/ui/widgets/source/widgets/wcm/FeedImporter.js
3) Add your scheme:
{
"text":"Jira Feed",
"value":"jira”
}

The Implementation
7
OSGi Bundle
1) Add service descriptors
@Service(value=Importer.class)
@Component(immediate = true, metatype = true)
@Properties({
@Property(name = "service.name", value = "Jira RSS Polling Importer"),
@Property(name = "service.description", value = "JIRA Polling Data Importer"),
@Property(name = "importer.scheme", value="jira") ,
@Property(name = "jira.username", description = "The JIRA service account to be used."),
@Property(name = "jira.password", description = "The JIRA servuce account password to be used."),
@Property(name = "xslt.path", description = "The JCR path to the XSLT to be applied to the Jira feed.")
})
2) Implement the importData method
public void importData(final String scheme, final String dataSource, final Resource resource) throws ImportException {}
