Welcome to the second Prototype Workshop, PW2. This Web page has been created specifically to provide ECS PW2 reviewers with a view of the process, objectives, content, and schedule of the PW. In addition, this page will hold the current status of the PW and when possible, preliminary screens of the prototypes. We hope that this increases communication and user feedback into the Prototype Workshop (PW) cycle by allowing local and remote reviewers the opportunity to see changes and influence upgrades on a week-to-week basis.
Prototype Workshop 2, held January 24-26, 1996 at ECS was another successful endeavour! Our thanks goes out to all those involved for all your time and effort. The EDHS link below provides you access to the PW2 Results Report. A listing of all comments received during the workshop hands-on testing and through the Comment Survey are available within the document appendices.
PW2 Results Report
The primary focus in PW2 will be to evaluate user interface implementation paradigms: web clients, web clients w/Java, and X/Motif. PW2 will also examine how best to support multiple levels of users (novice, intermediate, and expert).
PW content includes an advance look at the next increment of the ECS Client, prototypes (both internal and external) and screen mockups showing planned capabilities. PW2 will include the most current version of the ESST, a Web/Java prototype client which supports a subset of ESST functionality (search by discrete parameter; temporal and spatial search; results display and selection of results for browse), and three screen mockups showing subsetting, session management and coincident search. In addition, PW2 will include a version of the ASTER DAR client prototype and will evaluate two external prototypes: the UMCP Dynamic Query Prototype and the V0 WWW IMS.
The total content listing for PW2 is the following:
The ESST will include performance improvements in results rendering and new features such as access to V0 through the LIM, a search status dialog, the ability to save and load searches, and a fully implemented connection to the advertising service.
This will be a functional version of the ASTER DAR user interface only (no underlying communication with ASTER). It will show how the ASTER DAR will be used to specify and search a DAR database.
For PW2, we will provide a look at advanced web technology. The Web with Java prototype will showcase features supported by the Java programming language along with advanced capabilities of the Netscape browser (i.e., frames). Through a connection with the Local Information Manager (LIM), this web client will support basic search, results, and browse, thereby leveraging design and development already completed in the ESST.
This functional screen mockup will demonstrate the subsetting service user interface as proposed for ECS Release B.
This mockup will show how we plan to implement coincident search capability through the ECS Client and improves upon the approach taken in PW1.
The LIM will interface to the V0 Gateway and the Core Data Server Prototype, allowing PW2 to support multi-data server searches.
The V0 Gateway will provide the ability to perform inventory search and browse of V0 data through a V1 user interface. This capability helps to increase the amount and variety of data with which to evaluate the V1 user interfaces.
While there is no development work being done on the Data Dictionary for PW2, the dictionary will be populated with more and varied V0 metadata to enlarge and enrich the data pool available for searching.
This is the same service used in EP6.
For PW2, we are using the Core Data Server Prototype. This is the same prototype used in EP6.
The UMCP prototype is a dynamic query user interface that is designed to address three major obstacles: network performance, data volume, and data complexity. Through a two-phase query development process, the user is allowed to explore and eliminate undesired data sets prior to submitting requests for data across the network. This approach is oriented towards users who prefer an exploratory method for developing queries.
This is V0s first cut at a web interface. The version we'll be hosting is in beta release and typifies what an ECS web interface might look and feel like. The V0 WWW features an end-to-end capability from V0 guide information to search and order of V0 data. The search capability features search by parameter, source, sensor, data set, data center, time range, and geographic location, and also supports the ability to save and restore searches by URL. In addition, this prototype demonstrates creative use of standard web technology to support dependent valids, integrated browse and graphic selection of spatial parameters. This is a good chance to see what it would be like to interact with ECS through the web!
CDE will be shown to anyone who wants to see it, and will be used on some of the evaluation machines. We will not, however, be doing any formal evaluation of CDE itself.
We are planning on showing a video of the Battelle SPIRE system. The primary use for this system is as a tool to assist the scientist in research planning.
The preliminary scenarios have been sent out and comments have been received back. For all those who sent us comments, our thanks. Your input was most useful. We are in the process of finishing the final cuts of the scenarios to be used in the evaluations. Please stay tuned.
Please note!!!!! The workshop schedule was changed (as of December 4) in order to coordinate with the EGS Status Review. The new dates are January 24 to 26. I tried to reach everyone through e-mail regarding this. My apologies to anyone who is seeing this change for the first time.

Incremental Track (IT) - Illustrates the incremental track process and how it feeds to the formal track. Includes a schedule correlating the IT with formal track milestones.
User Prototype Evaluation Process - Good overview of how ECS users evaluate PWs, EPs, and other prototype systems.
