Marco

Inputs

Fields from a web form. An existing webservice which might be utilized is SQLTuple JSP. Predefined skims

Outputs

SQL query to select the desired skim. Some representation capturing the selection (history of the steps performed to obtain it?).

Task Description

Iteratively compose skims, specifying event cuts and output content. The user will have some standard/predefined skims. A user interface that allows the user to enter parameters for custom skims. Some explorative query to present preliminary results (e.g. count the number of records, some basic plot) A pre-defined set of plots could summarize the distribution of important parameters

Could be:

• simple web interface providing some plots and the possibility to enter parameters for cuts or to select predefined skims
• root files with the content of the TAG DB exported for analysis in Root
• JAS3

JAS3 seems the most flexible alternative and will be used for the initial prototype. A summary TTree or histograms will also be provided in ROOT format.

Whatever plotting or display service is used, it should provide the following functionality

• The ability to locate all collections resident on a site and any metadata associated with them.
• Plot all attributes as 1D and 2D plots
• Easy changing of cuts and summary of existing cuts.
• Display number of events

It would also be good if the service had the following features.

• The ability to store a state and restore it. This could simply mean that it can take its output as input.
• List the datasets associated with a selection. This implies a lookup in the DDM catalogs at CERN.

External Dependencies

• A functional TAG database.
• DDM access.

Questions/Comments

• Question:Jerry: The output goes where? Is it consumed by the SkimSelector or can the user capture the output and execute the query themselves?
