1. MDID Users Group VRA Conference 2010 Atlanta, GA

2. Vision and Guiding Principles Allow students and faculty to manage, discover, and aggregate digital media for intuitive and flexible delivery and presentation Embrace Web 2.0 and open access

3. Content Discovery Starts on front page Displays selection of images accessible to user

4. Explore Interface Keyword and facet driven Facets are based on Dublin Core Shows all records accessible to user Unauthenticated (anonymous) users see publicly accessible content

5. Sidebar: Role of Dublin Core MDID “knows” meaning of some Dublin Core fields Title Identifier Relations As many fields as possible should be mapped (directly or indirectly) to a Dublin Core field

6. Facets By default facets are broken up by words Phrases are possible Controlled vocabulary fields Examples: Creator, Period

7. Sidebar: Search Engine MDID uses Solr for all searching and facet creation Solr is an Open Source tool built on Lucene, which MDID2 uses Search behavior can be customized directly in Solr

8. External Content All searches also run against external sources MDID shared collections Flickr ARTstor

9. Multimedia Support Thumbnails are automatically generated Images Videos (still frame five seconds in) Audio (30 second waveform sample)

10. Sidebar: Supported Multimedia Formats MDID backend supports FFmpeg compatible formats; commonly available client side delivery tools may only support a subset MDID uses FFmpeg to identify files and to extract information Determine bandwidth and pixel dimensions Extract video frames Extract audio samples to create waveform

11. MediaViewer Replaces MDID2’s ImageViewer Complete rewrite with modern technologies Three modes: MediaViewer: Web (development complete) MediaViewer: Desktop (almost complete) MediaViewer: Package (under way) Compatible with both MDID2 and MDID3

12. MediaViewer: Web Runs in any modern browser on both Windows and Mac OS Requires Flash player version 10.0 or higher Runs in full screen mode with limited keyboard interaction Currently integrated with MDID2 demo sitehttp://mdid.org/demo/

16. MediaViewer: Desktop Built on Adobe AIR technology using same code as web version Requires a live Internet connection Easy web-based installation Will be released with MDID3 Will be backward compatible with MDID2

21. Accessibility Content discovery and management is possible without a mouse JavaScript Flash Certain viewers depend on JavaScript or Flash, e.g. MediaViewer

22. Vision and Guiding Principles Embrace Web 2.0 and open access Encourage content sharing between individuals, institutions, and the public Leverage collective intelligence through comments, ratings and tagging Engage students by allowing them to add, create, share, and manage content

23. Social Networking Features Stable URLs (permalinks) to all pages Tagging for records and presentations Comments

24. User Involvement Optionally all authenticated users can use MDID to manage their content Upload metadata and files Customize metadata on all records Create presentations By default these actions are invisible to all other users File uploads are optionally limited by quotas

25. Management Tools Built into web application Metadata import CSV VRA Core 4 Job management Long running tasks are executed asynchronously Job status is displayed in browser Administrators can monitor and control all jobs

26. Content Organization Metadata records and media files are organized separately Records are stored in Collections Media files are stored in Storage Areas

27. Collections can contain other collections Photography Landscapes JMU Photographs

28. The same collection can belong to multiple collections Photography JMU Artifacts Founding Documents Landscapes JMU Photographs JMU Photographs

29. Records and associated media Multiple files of different types can be associated with a single record Media File: john-doe.mp3 Type: audio/mpeg Record Title: Interview with John Doe Date: May 5, 2004 Media File: john-doe.pdf Type: application/pdf

30. Hierarchical Records If multiple files of the same type exist, each should have its own record Records can belong to at most one parent record and have no, one, or multiple child records Wilson Hall Front view Detail view

31. Viewers Viewers are tools that display a single record or a whole presentation on the web Viewers support a variety of presentation types: MediaViewer for slideshows Player for video or audio playlists Flash card generator Slideshow handout generator More viewers will be added to MDID over time

32. Viewers MDID determines which viewers fully or partially support an object or a presentation Mixing media types in a presentation is possible but may limit the number of viewers that are available When multiple files are associated with a single record in a presentation, viewers intelligently choose the appropriate file where possible

33. Records can belong to multiple collections JMU Photographs Architecture Wilson Hall Wilson Hall

34. Storage Areas Each Storage Area in MDID defines a physical storage area to hold media files Collection files can be spread across multiple storage areas rather than restricted to one physical directory Storage areas can hold files that belong to different collections

35. Storage Areas Storage areas can add functionality Automatically manage ZIP archives Produce streaming media links Physically organize files in subdirectories

36. Permissions Only three permissions Read Write Manage Can be set for users or user groups on Collections Storage Areas Presentations

37. Organizing collections to control access Goal: some records in a collection are available to the public, while others are not Solution 1: Create two collections and add them to a parent collection Photographs Public Private

38. Organizing collections to control access Goal: some records in a collection are available to the public, while others are not Solution 2: Create one private collections and add it to a public parent collection Photographs Private

39. Organizing Storage Areas to control access Goal: Only low quality video should be publicly available Solution: Store videos in different storage areas Low quality video storage Record High quality video storage

40. Customization Interface template is completely CSS based All colors are configured in one area Two master colors define basic color scheme Logos can be switched out HTML can be modified easily

41. PowerPoint Export MDID presentations as PPTX files Users choose from different themes Additional themes can easily be added Import PPT and PPTX files into MDID Converts all slides to images Slide quality not as good as an image export directly from PowerPoint Requires OpenOffice on server

42. Vision and Guiding Principles Continue to promote adoption of MDID beyond JMU Build MDID 3 using Open Source software Share MDID 3 through an Open Source license

43. Server Architecture MDID can be installed on any major operating system Windows Linux MacOS

44. Server Component Overview

45. Server Architecture Components can reside on one or multiple servers running any major operating system Components can be duplicated on multiple servers for redundancy or to support more load

46. Migrating from MDID2 Document any customizations Custom user authentication Clean up collection fields Map as many fields to Dublin Core as possible Migration tool will copy users, groups, collections, records, etc. Due to differences in data structures, migration results need to be reviewed before going live

47. MDID as a platform for building multimedia apps Developers can build custom multimedia applications on top of MDID Showcases for special collections Specialized interfaces for compound multimedia objects Simplified interfaces with unneeded functionality removed

48. JMUtube Allows faculty to manage and deliver video, audio and Adobe Presenter files Simple drag-and-drop playlist builder Integrated with JMU’s classroom recording system and Camtasia Relay
