--------------------------------
Summary: Improve Function Library For Jena Rules Engine
Key: JENA-1201
URL: https://issues.apache.org/jira/browse/JENA-1201
Project: Apache Jena
Issue Type: Improvement
Components: Jena
Affects Versions: Jena 3.1.1
Environment: any
Reporter: Paul Houle
The Jena Rules engine can use a better "standard library" of functions. The
plan for this project is:
(a) develop a list of candidate functions based on (i) sparql functions, (ii)
xpath/xquery functions, (iii) methods and functions from core Java classes such
as String, Math, etc. and (iv) other common string operations such as the
"ucfirst" function in PHP.
(b) work out some strategy to build out the stubs (use JDK8 "functional" idioms
or code generate the stubs?)
(c) build out the stubs
(d) update documentation
I volunteer because I am going to write these up as UDFs anyway...
