ARIADNE RepositorySoftware
Open Standards & Specifications
SQI - PLQL - SPI - OAI-PMH - RSS - CAM
Easy accessible API for search
Metadata schema support
IEEE LTSC LOM by default
Any schema with an xml binding
Open-source license
Out-of-the-box deployment8
Validate
Paste metadata record
e.g LOM instance
Select validation scheme uri
e.g http://ltsc.ieee.org/xsd/LOM/strict
Validate & Consult Validation Errors
Based on XSD Schema & Schematron Rules
http://bit.ly/90va7d9
Transform
Different Application Profiles
e.g ARIADNE AP to CGIAR AP
Different Metadata Schemes
e.g DC to IEEE LOM
Third-party Metadata to IEEE LOM
E.G
MD MD
10
Semi-Automatic Metadata Generation
Enrichment of metadata
Based on context
Different kind of detectors
language, keywords, technical information, etc.
