Project Definition

Build a system that allows users to create, compile, and run mashups of different services

Create a graphical user interface that is efficiently used by scientists, the military, and others who may not be able to easily access traditional computer peripherals

The project will focus on the user interface, compiling, and running service mashups

Rationale for Project

Allow for non-programmers to create mashups of web services

Provide a solid and easy starting template for experienced programmers

Offer users the ability to execute their mashups on public or private servers

Current Solutions

1. Yahoo! Pipes2. Google Mashup Editor3. Microsoft Popfly4. Intel Mash Maker5. IBM Lotus Mashup

Two main categories1. Pure editors2. Editors with community based

mash-up recommendations

The majority of these editors focus on web services only, with the aim at assisting experts at creating mashups of services that will be accessible via the Internet.

Current Solutions: Limitations Does not allow private hosting of

mashup (Yahoo! Pipes) Only offering pre-defined data feeds

and web-services, limiting the creativity of the user

Code-based editors like Google Mashup Editor offer more power but also more complexities


04/13/2023

MVP-E: Approach Focus on the user interface (creation),

registry (storage), execution engine (interpretation)

Utilize OWL, RDF, and SOAP messages to ensure interoperability with other programs and advance the Semantic Web

Create a graphical user interface that supports multi-touch manipulation as well as the traditional mouse and keyboard

Use Case: Happy Hour CrimesNarrative Web Services Given all the bars within the

city of Philadelphia and their known happy hours, match this data up with minor crimes such as vandalism, public indecencies, gambling, speeding, etc. within 5 city blocks of bar. Plot this data on a map for users. This allows users to take clients, relatives, etc. to bars that are more likely to have fewer nearby crimes.
