In this report, we prove the undecidability of Core XPath 1.0 (CXP) [6] extended with an Inflationary Fixed Point (IFP) operator.  ...  The second author is supported NWO grant 639.021.508 and by ERC Advanced Grant Webdam on Foundation of Web data management. We thank Anuj Dawar for a useful discussion.  ...  Our main result states that, already for the downwardlooking fragment of Core XPath 1.0 with the inflationary fixed point operator (CXP+IFP), satisfiability is undecidable.  ...

This fracturing stifles innovation as application builders have to cope not only with one Web stack (e.g., XML technology) but with several ones, each of considerable complexity.  ...  Exposing not only human-centered information, but machine-processable data on the Web is one of the commonalities of recent Web trends.  ...  Xcerpt query terms have, as pointed out above, some similarity with XPath queries. Containment for various fragments of XPath is surveyed in [138] , both in absence and in presence of a DTD.  ...

Based on an RDFS schema, "inference rules" can be specified, for instance the transitivity of the class hierarchy, or the type of an untyped resource that has a property associated with a known domain.  ...  RDF does not describe which properties can be associated with a class, but instead the domain and range of a property.  ...  XPath path expressions (disregarding XPath predicates for the moment) fall into this category with closure axes such as descendant.  ...
