+
+Another initiative to manage OSGi&#153; dependencies with Ivy is the project <a href="http://felix.apache.org/site/apache-felix-sigil.html">Apache
Felix Sigil&#153;</a>. We will try to explain here the different approach taken
there compared to the build-in OSGi capabilities of Ivy.
+
+<h1>A different approach</h1>
+
+The difference between the build-in OSGi resolver and the Sigil one is about the "engine"
used to resolve dependencies.
+
+The build-in OSGi resolver is <i>obviously</i> using the Ivy engine to do the
resolution of the dependencies. The OSGi capability of Ivy is mainly due to the dependency
parser implemented to understand the OSGi metadata in a MANIFEST.MF.
+
+On the other hand, Sigil is using a separate "engine" to do the resolution, an engine which
is dedicated to understand the OSGi metadata and their semantics.
+
+The immediate consequence of this difference is that the build-in resolver is probably less
accurate than the Sigil one as to understand the OSGi dependencies semantics. As explained
in this <a href="osgi-mapping.html">page</a>, the OSGi model doesn't fit well
into the Ivy one.
+
+
+<b>TO BE CONFIRMED</b>But then the drawback of Sigil is that it is less integrated
with Ivy, and once the resolution happens in its dedicated enine, no conflit resolver and
no resolver chaining can happen.
