HOW TO SETUP EMMA
-----------------
EMMA matchmaker consists of two different filters that can be applied to any 
other matchmaker to enhance performance with a contained penalty.

Both filters depend on another matchmaker implementation to be enhanced by 
the provided SPARQL-based filters. To setup the internal matchmaker used by 
EMMA, one can edit the "emma.properties" property file to specify a matchmaker 
implementation. Thus, "emma.qsome.internalMatchmaker" property points to the 
XML definition of the matchmaker plugin used by "EMMA (Qsome)" filter, and 
"emma.qall.internalMatchmaker" defines the matchmaker used by "EMMA (Qall)", 
similarly. Both properties have to include the relative path to the 
corresponding XML file from the <SME2_DIR>/plugin/ directory.

By default, EMMA uses OWLS-MX3 (M3) implementation, but it can be configured 
to use another plugin properly installed in <SME2_DIR>/plugin directory.

REQUIRED LIBRARIES
------------------
EMMA has a dependency with OWL-S API version 2.0. OWL-S API can be downloaded 
at:

http://on.cs.unibas.ch/maven/repository/ch/unibas/on/owls-api/2.0/owls-api-2.0-bin.zip

In the case required libraries are missing in the EMMA plugin directory, 
please copy all the jar files on the OWL-S API 2.0 distribution into 
<SME2_DIR>/plugin/emma/lib directory.
