  <dc:description>D-Net Software Toolikt

The D-NET Software Toolkit is a system that offers functionalities for the collection (“harvesting”), transformation, aggregation, and indexing of metadata records collected from an arbitrary number of data sources, complying with different protocols and data exchange formats. D-NET sets a workflow language, which developers can use to combine a variety of D-NET data management services, configure them to handle data according to given data models, and pipeline them into autonomic data processing workflows.

This software package is a simplified version of the D-Net toolkit and consists of a web application with a minimal set of services for:


	
	Collection of metadata records in oai_dc format via OAI-PMH, FTP, local file system, HTTP.
	
	
	Transformation of the collected metadata records into an internal format named DMF (Driver Metadata Format)
	
	
	Indexing of DMF records in a Solr full-text index
	
	
	OAI-PMH export of aggregated metadata records in DMF and oai_dc formats. More formats can be added at runtime by providing a dedicated XSLT from DMF to the desired target format.
	


Major changes in version 1.3.0


	OAI Publisher:
	
		fixed cache management
		fixed oai consistency (post feed) workflow branch
		fixed deletion of content when workflow of data sources are deleted
	
	
	D-Net enabling services:
	
		using cache for subscription access
		support only one subscription registry
	
	
	Mongo based services (mdstore, oaistore, wf logging):
	
		using API of mongo-java-driver 3.2.2, removed usage of deprecated methods
		tracking the number of stored records to possibly highlight the collection of records with the same identifier
	
	
	GUI:
	
		enabling deletion of APIs via GUI
		enabling editing of metadata_identifier_path
		more info available in the datasource section
		removed map of data sources (TODO: adapt to the new google map API)
	
	
	Metadata collection:
	
		handling HTML illegal entities in collected XMLs
	
	
	Indexing:
	
		default query operator for "bag of words" queries set to AND instead of OR
	
	
	Workflow manager
	
		do not launch workflows that were scheduled for execution during a pause of the aggregation system ("prepare for shutdown")
