RIB Overview

» RIB is a software package for building and maintaining WWW metadata repositories.

» Primary design goals

• Promote software reuse

• Provide interoperability

» Primary features

• Tools to build and manage metadata repositories

• Automatically generated, browseable, searchable HTML catalogs

• Metadata encoded using XML, based on IEEE standard for

software cataloging on the Internet (BIDM)

• Able to share information through interoperations among repositories using similar data models

RIB History

» Evolution of RIB

• RIB 1.0 – first version of RIB

• RIB 2.0 – complete rewrite of 1.0 with many new features introduced:� Use of XML and Database

� Java applet admin interface

� Object approval operation

• RIB 2.1 – file upload feature added

• RIB 2.2 – interoperation feature enhanced

• RIB 3.0 – the Java RIB, complete rewrite of 2.x as a servlet-enabled web application� Reduce installation complexity

� Reduce code maintenance complexity

� Improve Flexibility

� Improve Reliability

Release of RIB 3.0

» Tested RIB 3.0 with the latest versions of its components:

• Java 1.5.0 (JAXP package renamed)

• Tomcat 5.5.9

• MySQL 4.1.7 (internal date format changed)

» Updated the RIB documentations:

• RIB user manual (distributed with the package)

• RIB 3.0 installation guide (posted on the RIB website)

» Developed a web configuration interface for RIB 3.0 (good idea from Don)

» Released RIB 3.0 beta officially

» Maintaining RIB 3.0

• Bug fixes

• User customizations

Selection of RIB 3.0 Features

» Provide different views for different users:

• General

publics

• Repositoryadministrators

• RIBadministrator

5


» Able to show objects from all classes in the catalog


» Display object information as an expandable object-tree

6


» RIB 3.0 web configuration interface

» Installed both RIB 2.2 and RIB 3.0 on rib.cs.utk.edu (thanks to Don)

» Wrote a Java program to automatically import repositories from RIB 2.2 to RIB 3.0

» Went inside each imported repository in RIB 3.0 to manually edit non-importable contents such as:

• Interoperations

• Customized templates

• Uploaded files

» Migrated all RIB 2.2 repositories to RIB 3.0. Now available at:

• http://rib.cs.utk.edu/rib3app/top

Migration From RIB 2.2 to RIB 3.0

Improvements to RIB 3.0

» Improvements to the file upload feature

• Able to manage (upload/view/delete) files in a common web interface

• Able to do “upload and attach” as a one-step operation in the Java admin interface


8


» Improvements to the join feature

• Able to refine join conditions to perform “selections”on join results (based on vocabulary controlled attributes)

• Able to make column and row headings stay visible while scrolling (thanks to Don again)


9


» Improvement to the search feature

• Able to search objects based on their relationships to other objects (currently working on)

Integration of RIB With Other Tools

» RIB with ReST

• ReST is an effort to reduce the difficulties involved in distributing, maintaining, and monitoring software in distributed environments

• Built a RIB 3.0 install package specifically for ReST, and made available through Java Web Start

10



» RIB with TAU and PAPI

• Developed new perfdmf tools

� Able to retrieve information from existing RIB repositories for creating TAU applications/experiments and save into a TAU recognizable format

� Able to retrieve hardware information from the machine the tool is running on for creating TAU experiments, through PAPI Java call get_hardware_info() (thanks to Haihang)

• Made a TAU patch and tested for the latest version of TAU 2.14.7

11

Future Work

» Resolve database compatibility issues to accommodate ideally any JDBC compatible database

» Provide tools to convert existing metadata into RIB recognizable format – simplify the metadata creation process

» Make RIB work better with other tools

» Create other customizable features upon user requests
