2 Open Document Architecture (T.411/1993)
Document: A structured amount of information intended for human perception, that may be interchanged as a unit between users and/or systems. The purpose of the document architecture is to facilitate the interchange of documents in a manner such that: – different types of content, including text, image, graphic and audio, can coexist within a document; – the intentions of a document originator with respect to the logical and layout structure of a document can be transmitted to a recipient. It also supports security aspects such as – protection against unauthorized semantic knowledge of parts of a document; – detection of discrepancies between the claimed and actual source and content of part of the document.

3 Roles and Players in GII (Y.110/1998)
Structural roles are roles which are all directed towards a particular product or set of products. They normally are set in a chain, called the primary value chain, which starts with the raw materials for the product and ends with the retailing of the product to end users. The information industry has a set of structural roles which form a primary value chain including: Information ownership role; Provision of information and related content role; Provision of information-based services role; End user role

6 Multimedia Service Reference Model (F.700/2000)
Multimedia service: Multimedia services are telecommunication services that handle two or more types of media in a synchronized way from the user's point of view. A multimedia service may involve multiple parties, multiple connections, and the addition or deletion of resources and users within a single communication session. Representation medium: The type of the information in its coded form, ready for transmission. Examples of representation media are: Representation media Possible coded forms characters or text ASCII, EBCDIC graphics CEPT, NAPLPS or CAPTAIN videotex, CGM Audio TSS, G.711, MIDI, future MPEG/Audio standard still picture Fax G3/G4, JPEG standard moving picture (video) H.261, H.262, H.263 or Sequence ITU-R Recommendation BT.601

7 Multimedia Service Elements (F.700/2000)
The MSEs contain all the control features and the processing functions associated with the service and communication task levels, possibly but not necessarily with the media component level (for instance the coding and decoding process belongs to the media component). Each service uses several MSEs, and a given MSE may be used by different services. An MSE is a completely independent modular entity. However an MSE may call upon another MSE when particular functions are required. For instance security functions provided by an MSE may be used by other MSEs, e.g. for authentication before accessing a document or performing a task or for encryption of a confidential document. MSEs may also exchange data (e.g. call control may need data from the directory). The control features are usually embodied in protocols independent from the transmission systems. Their functional descriptions are independent from the basic protocol, but the set of specific commands and messages associated with the protocol has to support the required functions.

9 ? Old time Data vs Today Data Data Old time Data Today Data
structured data is comprised of clearly defined data types whose pattern makes them easily searchable unstructured data is comprised of data that is usually not as easily searchable, including formats like audio, video, and social media postings Real time Data Non-Real time Data
