The GLIFOS - social media toolset automates the production, cataloguing, digital preservation, access, and sharing of rich-media over diverse presentation devices (PCs, PDAs, smart phones), data transport platforms (Web, streaming media, CDs, DVDs), and operating systems (Windows, Mac OS, Linux). Moreover, the use of an XML-based open specification, which is technology-, platform- and format-independent, guarantees content portability to platforms that will arise in the future (digital preservation).
gmPlayer, gmPocket, gmNotes: Accessing Rich-Media Content
Rich-media content integrates video, text, and images to such an extent that it transmits the richness of video (a manufacturing process, a doctor’s bedside manner, the passion of a lecturer) without losing the functionality of a book: finding a word, studying a diagram in detail, making annotations, bookmarking specific sections, and extracting references. gmPlayer synchronizes video and audio content with an unlimited number of tables of content, transcripts in one or more languages, references, slides, and student notes via the gmNotes functionality.
gmCreator: Producing Rich-Media Content
gmCreator automates the production of rich-media content to the point where it is faster, less costly, and more effective to create a complete course using rich-media than it is to create the equivalent course materials in print form. It is generally easier to videotape an excellent professor while he or she teaches a course, than it is to have this busy professor take time off to write a textbook or an academic paper.
At the same time, less effort is needed to explain and learn visual and auditory concepts or manual procedures via rich-media than via elaborated textual descriptions.
gmWiki: Sharing Rich-Media
Rich-media integrates multiple media (video and/or audio) within the same content page. Social rich-media allows for collaborative content creation via a wiki cooperative environment, where one can manage an unlimited number of synchronized content (transcript, translations, table of contents, presentation slides, photographs pictures) per video.
gmLibrary: Content Cataloguing and Access
gmLibrary and gmPlayer mirror the traditional structure of library catalogs and indexes in order to allow access to any video fragment, at any time, from virtually anywhere. High speed networks (10/100 Mbps or faster) have become common on today's university and corporate campuses. At such speeds, high quality streamed video can be almost compared to dvd quality. gmLibrary finds content by its bibliographic record, metadata description, and fulltext from tables of content and transcripts. And gmPlayer takes you directly to the segment of the video that is related to a section, or even a word. Unlike many closed courseware models, the digital library model makes it natural to reference and reuse content in part or as a whole.
GML & gmSkins: Digital Preservation
The use of an XML-based open specification (GML), which is technology-, platform-, and format-independent, guarantees content portability to diverse platforms in use today (PCs, PDAs, smartphones, tablet PCs), as well as those that will arise in the future, thus maintaining the usefulness of the contents even if technology changes, and even if institutional image or preferences change. Using gmSkins, the same content can be easily repurposed for various data transport platforms (Web, streaming media, CDs, DVDs) and presentation devices.
It is possible to implement GLIFOS - social media in incremental steps, according to each institution's needs:
