I enjoyed reading the paper. I suggest the following changes to the introductory section to improve readability:
Linked Data has emerged as a principled, flexible, open standard based approach to share, integrate and link heterogenous and disparate data across tools and data silos both within and across organizational boundaries. It leverages well-established web architecture concepts (e.g., resources identified by URIs, and the HTTP communication protocol), and introduces RDF as its fundamental data model with SPARQL as its query language. While much attention has been devoted to the use of Linked Data principles to share and access information in the growing Web of open Data, at IBM, we have successfully relied on the Linked Data approach as an architectural style for addressing the issue of integrating data and function across a suite of software applications [1].
In the context of Linked Data for Application Integration, a key challenge that we had to address was the lack of any standard mechanism to validate RDF data. Standard web ontology languages (e.g. RDF Schema and OWL) have been well documented [2, 3, 4, 5, 6] as being inadequate as validation and integrity constraint languages for RDF. They were primarily designed for distributed environments where any single information provider or consumer is only assumed to have partial information. For example, their Open World Assumption (OWA ) semantics and the absence of Unique Name Assumption (UNA ) trigger the inference of new facts where the Closed World Assumption (CWA) of traditional constraint languages (e.g. XML Schema or RelaxNG for XML, Data Definition Language for relational data, etc.) would directly trigger constraint violations.
In this paper, we start by describing the motivation driving the need for a constraint language for RDF data. We then present some important requirements for such a language. Finally, we briefly introduce OSLC (Open Standards for Lifecycle Collaboration) Resource Shape, our solution for addressing RDF data validation needs that was developed in the context of using Linked Data for application integration.
In the closing sentence of the introduction section, I suggest adding a reference link when first mentioning OSLC.

Subject: [reporting-workgroup] W3C RDF Validation Workshop, Sept 10/11 - OSLC Resource Shapes
Sent by: [email protected]
W3C has accepted the paper on OSLC Resource Shapes which was submitted by
myself and Achille. [1] I am planning to attend. I'd therefore like to
collect any further feedback and requirements. I know that the Query
Builder workgroup is proposing extensions to the spec.
I expect that the result of the workshop will be a consolidated set of
requirements as input to a new W3C spec, which I hope will be similar to
OSLC Resource Shapes. This could be the OSLC 3.0 version of the Resource
Shape spec.
