SimpleDL is standards-based and supports numerous industry standards including Unicode, Qualified Dublin Core, XML, and OAI-PMH. The metadata is based on Dublin Core, a flexible extensible metadata standard created by OCLC in 1995. Dublin Core has been accepted as a NISO standard.
Digital items can be added to a SimpleDL digital collection through standard web browsers and standard web interfaces. Items can be added one at a time or in batches. The digital collections reside on a server, either locally or at the firm.
Additional functions are available such as creating and editing metadata templates, administering the use of controlled vocabularies, importing metadata (tab-delimited text), exporting metadata in XML, generating OCR during the import-export using the OCR Extension, and viewing statistical reports.
Searching abilities are provided by a custom Solr build, permanent storage is provided by the MySQL database engine, and pages are served through the Apache HTTP Server and PHP. The software has an option to store and deliver the digital documents with Amazon S3 to provide high durability of files. Collections hosted by SimpleDL utilize Amazon EC2 servers.
