Removal and addition of FS between views
Hi,
(Excuse me if this is a duplicated post.)
I tried the following code but got error
" is over view "_InitialView" and cannot be added to indexes
associated with the different view "created".
at org.apache.uima.cas.impl.CASImpl.addFsToIndexes(CASImpl.java:3880)
at org.apache.uima.jcas.impl.JCasImpl.addFsToIndexes(JCasImpl.java:1076)
...
I checked the source code of UIMA but it seems that the removal of the
FS was not made properly.
My question is that:
1. Is it impossible to share FeatureStructures between multi-views in
a single CAS?
2. If yes, then remove a FS from a view and add it to another view is
also impossible?
Thanks!

Inside JCasAnnotatorImplBase with the multi-view settings:
public void process(JCas aJCas) throws AnalysisEngineProcessException {
TypeSystem typeSystem = aJCas.getTypeSystem();
try {
JCas initialView = aJCas.getView("_InitialView");
JCas createdView = initialView.createView("created");
// JCas createdView = aJCas.createView("created");
FSIterator allIndexedFS =
initialView.getFSIndexRepository().getAllIndexedFS(typeSystem.getTopType());
while (allIndexedFS.hasNext()) {
TOP top = (TOP) allIndexedFS.next();
// I think it should work without removing... top.getView() may have
returned illegal handle though it should be removed from indexes
initialView.removeFsFromIndexes(top);
// top.removeFromIndexes();
createdView.addFsToIndexes(top);
}
}
} catch (CASException e) {
e.printStackTrace();
}
}

RE: Rules engine as an annotator
Posted by Pascal Coupet <pa...@temis.com>.
Hi Thilo,
I don't know about a free JSR 94. The following article from SUN
provides a reference implementation on top of JESS.
JAVAhttp://java.sun.com/developer/technicalArticles/J2SE/JavaRule.html
JSR 94 defines the way to communicate with the engine but not the rule
language itself witch is specific to each implementation.

not that I know of. Is there a free JSR 94 implementation that could
be wrapped?

If I can make a business case for it here I will give it a shot. It is
something we could use anyway.

And it's even Apache licensed, way to go! Now we just need
somebody to wrap it in an annotator. Volunteers?

Rules engine as an annotator

Do somebody knows if there is a java rule engine that has been
encapsulated as an UIMA annotator or if a generic annotator toward JSR
94 exists or if somebody planned this?

This error must be for an annotation FS. As mentioned in the other
reply, an annotation FS can only be indexed in the View associated
with the annotation's Sofa.

Except for annotation FS, an FS can be added to the index of multiple
views. The sharing of an annotation FS between views is accomplished,
for example, by creating a reference from an FS indexed in view-A to
an annotation FS whose Sofa is associated with view-B.
Hope this is becoming clearer,
Eddie
