Goals
•	Realize the maximum value of the editorial content you create and acquire!
Goals
–	Producers will have access to all content created by all productions at any time, after its release. This will enable us to:
•	Provide on-demand access to multimedia resources
•	Streamline the production process 
•	Facilitate concurrent production for various media by various production teams
Goals
–	This will enable us to:
•	Support consistent content for broadcast, distribution, publicity, and promotion
•	Simplify access 
•	Economize by reusing WGBH-owned assets before purchasing assets
Goals
–	Educational users should be able to access editorial content:
•	Provide on-demand access to digital video and other multimedia resources to enhance learning and teaching.
•	For teachers and students, editorial content will be organized to facilitate its use within curricular frameworks or to meet particular educational goals.
Goals
–	Educational users should be able to access editorial content:
•	Include information in a variety of formats— streaming video from the broadcast series and selected outtakes including interviews and interview transcripts, animation, archival and field photographs gathered during production, as well as excerpts from significant print sources (articles, books, journals) used in research for our series.
Goals
–	General users should be able to access editorial content:
•	As full-length programs or searchable program elements
•	Assets should be available in digital or physical formats
•	Supplementary and complementary materials
Goals
–	General users should be able to access editorial content:
•	On a variety of delivery platforms
•	At user-specified levels of quality
•	In a user-specified format
•	At a user-specified time
Goals
–	Archive
•	Content will be organized, preserved and maintained so that it will be available now and in the future.
Interconnectedness of all things.
–	Production / Post Production 
–	Master Control
–	Internet /  Broadband
–	Distance Education
–	Customer Relations
–	PBS Interconnection System
–	Archives / Preservation
