    13. 13. ARIADNE Repository Software 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 deployment 8
    14. 14. 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/90va7d 9
