Web User Interface Interest Related Work

SciencePipes.org Web User Interface (Cornell)

Technology:

• Java 1.5
• Hibernate 3
• Spring 2.5 and Spring Security (Acegi)

Implementation Infrastructure:

• MySQL (very few MySQL-specific features used)
• WebSphere App. Server (nothing IBM-specific knowingly used)
• Eclipse used for development

UI Features:

• workflow management
• browse
• search
• upload
• copy
• version
• delete
• download
• parameter management
• custom default values
• custom parameter prompts
• designating parameters as required
• expose subset of parameters for new values when workflow is run
• job management - a job is a workflow that is to be executed with specificied parameters
• see status
• cancel job
• delete job
• workflow results management
• see results from a particular job
• see results from the most recent run
• output is URL accessible and can be used as a permanent web resource
• output from a specific job can be referenced individually
• output from the most recent run of a job can be referenced as a permalink
• "community" tools
• tagging
• favorites
• rating
• comments
• user account management
• login/logout/remember me
• create/edit user account
• password reminder

Backend Features:

• actor management
• filters are used to replace normal Kepler/Ptolemy actors with compatible actors that are aware of the output repository
• not all Kepler/Ptolemy IO actors have replacements yet
• actor replacements utilize Spring for configuration
• job engine interface
• an engine takes a job and runs it in its entirety
• engines run in any Kepler-compatible JVM
• scalable by adding more JVMs (on the same machine or other machines)
• size of thread pools that engines utilize can be customized to the JVM/machine resources
• workflow repository interface
• Hibernate/MySQL Implementation
• MoML storage flexibility
• stored in DB as BLOB
• as URL reference
• obvious potential for other implementations utilizing MetaCat or Fedora Commons
• output repository interface
• metadata (size, mime-type)
• Hibernate/MySQL Implementation
• content stored in DB as BLOB
• parameter repository interface
• Hibernate/MySQL Implementation
• also handles one-time use job parameters
