LBNL Image Library -- Project plan
Image-Based Information Management and Access in the Scientific Environment
Bill Johnston, Imaging and Distributed Computing Group, LBNL
(wejohnston@lbl.gov)
Overall Goals
- Create an LBNL-wide digital information management system for text, image, video, audio, and data objects, and multimedia combinations of these objects
- Use this management system to organize and maintain the objects, and present the resulting information and knowledge to a wide audience
- Provide operational capabilities adequate for a large, multidisciplinary scientific institution:
- Mechanisms that ensure physical integrity of corporate knowledge
- Both universal and controlled access to LBNL knowledge
- Long-term indexability (unique accession / object identifiers)
- "Natural" and convenient access across most platforms
Approach
- Use the World Wide Web's proven ability to organize and present large amounts of diverse information that is managed by many different people
- Specifically address the organization, storage, retrieval, and annotation of large collections of images by the scientific groups that generate those images (Initiate a sufficient level of dialogue to understand the wider issues and potential uses)
- Build a prototype system around a small number of specific applications
- Use mostly existing tools so that a prototype system can be operational in the near-term
- Design a system that accommodates both text and image searching and browsing, as well as some "relational" capabilities
Expected Benefits of the Approach
- Direct involvement of the knowledge generators in the organization and maintenance of the information
- An easily used mechanism for allowing multiple views of data
- Wide availability of information (with controlled access) through the platform independent design of the WWW
- Much better data integrity and access (through a "natural integration" with institutional tertiary storage (the LBNL Mass Storage System))
Design Goals
- Provide simple mechanisms for owner specification of access control
- Provide non-intrusive mechanisms for coupling auxiliary- and meta- data to archive data
- Ensure that instantiated and non-instantiated referencing is easy and durable
- Accommodate both text and image searching and browsing, as well as some "relational" extraction capabilities
- Provide image and image meta-data browsing
- Provide for "high speed" access (i.e. access limited by end-user workstation)
- Accommodate derived data in a natural and consistent way, provide easy "pedigree" tracking for derived data
- Provide mechanisms for maintaining user-application structured views of the data without incorporating this structure information into the basic storage scenario
Specific Objectives
- Create a Web-based image management system that provides for:
- Extensible, annotated, modifiable, and easily accessed image archives
- "Easy" data-entry for images and annotations by data owners, digital librarians, analysts, etc. (e.g. scientific groups, Technical Photography, graphics artists)
- Fast access image storage facility
- Services that provide physical and logical integrity of information
- Create a Mosaic-based environment that provides for:
- Image "browsing" and focused search capability based on the text annotations
- Retrieval and manipulation of image data and associated textual information
- (LBNL Image Library illustrates some prototype capabilities - see http://www-itg.lbl.gov/ImgLib/welcome.html)
- Create tools and expertise that enable easily building and modifying the annotated image database
- Establish conventions for structuring image databases that will support scientific work groups
- Build tools that automatically populate these structures with original and derived image data, and the associated textual information
- Build tools that allow for modifying, augmenting, and updating this information based on owner defined access permissions (these tools should stay as close as possible to the WWW/Mosaic style of interaction for each of the supported platforms)
- Train digital librarians / digital photographers in the use of this technology
- Build several example, production databases in order to refine and validate the approach
