 ====== Migrating to KnowRob 2.0 ======
+**This page is a work in progress**
 The current master branch contains a redesign of KnowRob. The redesign changes the way how Knowrob has to be included into your project. Additionally some queries were replaced.
+===== Changes in the project dependencies and imports =====
+===== Migration of commonly used queries =====
+==== Registering of old KnowRob packages =====
+Many of the packages of the old knowrob/knowrob repository, e.g. knowrob_common or knowrob_vis have been merged into one knowrob package. Therefore calls of the form
+<code prolog>?- register_ros_package(knowrob_common).
+?- register_ros_package(knowrob_vis).</code>
+can be replaced by
+<code prolog>
+?- register_ros_package(knowrob).
+</code>
+==== Loading .owl files =====
+OWL files where loadid
+| <code prolog>?- owl_parser:owl_parse('package://knowrob_yourpackage/owl/yourontology.owl').
+?- rdf_db:rdf_register_prefix(
+yourontology, 'http://knowrob_yourpackage/owl/yourontology.owl#', [keep(true)]).
+</code>    | <code prolog>
+?- tripledb_load(

+       namespace(
+           yourontology,
+           'http://knowrob_yourpackage/owl/yourontology.owl#'
+       )
+    ]).
+</code>    | If you want to load the owl file and set a namespace |
+| <code prolog>?- owl_parser:owl_parse('package://knowrob_yourpackage/owl/yourontology.owl').
+</code>    | <code prolog>
+?- tripledb_load('package://knowrob_yourpackage/owl/yourontology.owl').
