XML Security Generic Hybrid Ciphers
Generic hybrid ciphers allow for a consistent treatment of asymmetric ciphers when encrypting data and consist of a key encapsulation algorithm with associated parameters and a data encapsulation algorithm with associated parameters. Further, the key encapsulation algorithms introduced in this specification have attractive security properties. This informative document augments XML Encryption Version 1.1 [XMLENC-CORE1] by defining algorithms, XML types and elements necessary to enable use of generic hybrid ciphers in XML Security applications, and reserving identifiers for those algorithms…

XML Security 2.0 Requirements and Design Considerations
This document outlines use cases, requirements and design choices for XML Security 2.0, specifically Canonical XML 2.0 and XML Signature 2.0. It includes a proposed simplification of the XML Signature Transform mechanism, intended to enhance security, performance, streamability and to ease adoption.

SPARQL Query Results XML Format (Second Edition)
RDF is a flexible, extensible way to represent information aboutWorld Wide Web resources. It is used to represent, among otherthings, personal information, social networks, metadata aboutdigital artifacts like music and images, as well as provide a meansof integration over disparate sources of information. Astandardized query language for RDF data with multipleimplementations offers developers and end users a way to write andto consume the results of queries across this wide range ofinformation.This document describes an XML format for the variable bindingand boolean results formats provided…

SPARQL 1.1 Entailment Regimes
SPARQL is a query language and a protocol for data that isstored natively as RDF or viewed as RDF via middleware. The mainmechanism for computing query results in SPARQL is subgraphmatching: RDF triples in both the queried RDF data and the querypattern are interpreted as nodes and edges of directed graphs, andthe resulting query graph is matched to the data graph usingvariables as wild cards. Various W3C standards, including RDF and OWL, providesemantic interpretations for RDF graphs that allow additional RDFstatements to be inferred from explicitly given assertions. Manyapplications that rely…

SPARQL 1.1 Federated Query
RDF is a directed, labeled graph data format for representing information in the Web. SPARQL can be used to express queries across diverse data sources, whether the data is stored natively as RDF or viewed as RDF via middleware. This specification defines the syntax and semantics of SPARQL 1.1 Federated Query extension for executing queries distributed over different SPARQL endpoints. The SERVICE keyword extends SPARQL 1.1 to support queries that merge data distributed across the Web.

SPARQL 1.1 Graph Store HTTP Protocol
This document describes the use of HTTP operations for thepurpose of managing a collection of RDF graphs. This interface isan alternative to the SPARQL 1.1 Update protocol. Most of theoperations defined here can be performed using that interface, butfor some clients or servers, this interface may be easier toimplement or work with. This specification may serve as anon-normative suggestion for HTTP operations on RDF graphs whichare managed outside of a SPARQL 1.1 graph store.

SPARQL 1.1 Protocol
The SPARQL Protocol and RDF Query Language (SPARQL) is a query language and protocol for RDF. This document specifies the SPARQL Protocol; it describes a means for conveying SPARQL queries and updates to a SPARQL processing service and returning the results via HTTP to the entity that requested them. This protocol was developed by the W3C SPARQL Working Group, part of the Semantic Web Activity as described in the activity statement .

SPARQL 1.1 Query Language
RDF is a directed, labeled graph data format for representing information in the Web. This specification defines the syntax and semantics of the SPARQL query language for RDF. SPARQL can be used to express queries across diverse data sources, whether the data is stored natively as RDF or viewed as RDF via middleware. SPARQL contains capabilities for querying required and optional graph patterns along with their conjunctions and disjunctions. SPARQL also supports aggregation, subqueries, negation, creating values by expressions, extensible value testing, and constraining queries by source RDF…
