QML Query Markup Language

Welcome to the QML home page!

QML is a markup language for constructing Web-based query interfaces to SQL databases. Our goal is to make it easier for scientists - non computer experts who may not be proficient in query languages and database techniques - to retrieve information from remote scientific databases using a web browser.

Here you can find:

• QML documentation
• Instructions on downloading QML
• Differences in functionality between QML and HyperSQL
• a QML example (and QML source)
• a QML re-implementation of Joe and Sherry's Lichen Synoptic Key (and QML source)
• a multi-step example (and QML source)
• Use of QML to create a bar graph (and QML source).
• An example of nested database queries (in this case, in a mycology bibliography lookup - and QML source).
