The aim of this document is to provide an overview of best practices in on-demand provisioning of infrastructure services that includes both traditional Network Resources Provisioning Systems (NRPS) and emerging Cloud based infrastructure services. These provisioning processes must be both sufficiently explicit and flexible to dynamically instantiate complex task or project oriented infrastructures comprising of compute, storage, and application resources, as well network infrastructures interconnect them.

The proposed document summarises discussions among members of the OGF ISoD Research Group and aims to facilitate conversations on achieving interoperability, and effective use and development of modern and future infrastructure services provisioning systems.

This document describes a set of normative schemas which allow the description of computer network topologies.

The goal of the Authorization Interoperability activity is providing interoperability between middleware and authorization infrastructures. This is achieved by designing and implementing an authorization protocol common to OSG VO services, EGEE, Globus, and Condor. This protocol is based on the SAML profile of XACML v2.0 [XACML]. The C library that implements the profile is provided by the Globus Toolkit security group; the JAVA library by the SWITCH group of EGEE.

The authorization protocol is used by Policy Enforcement Points (PEP), i.e. resource gateways, to interact with Policy Decision Points (PDP), i.e. repository of authorization policies. For each access request, the PDP informs the PEP on whether access is granted or denied and the conditions to be enforced if access if granted. These conditions are expressed in the form of XACML Obligations and are the mechanism to restrict privileges at Grid resources.

For resources to be shared, sites must be able to exchange basic accounting and usage data in a common format. This document describes a common format which enables the exchange of basic accounting and usage data from different resources. This record format is intended to facilitate the sharing of usage information, particularly in the area of the accounting of jobs, computing, memory, storage and cloud usage but with a structure that allows an easy extension to other resources. This document describes the Usage Record components both in natural language form and annotated XML.

This document does not address how these records should be used, nor does it attempt to dictate the format in which the accounting records are stored. Instead, it defines a common exchange format. Furthermore, nothing is said regarding the communication mechanisms employed to exchange the records, i.e. transport layer, framing, authentication, integrity, etc.

The purpose of this document is to specify the syntax and semantics of the Activity Instance Description. An "activity", in this context, is a unit of work to be executed on a distributed system. It can be a job, a task, a data processing operation, a data access operation, an application execution, a program execution or a Web Service invocation. The Activity Instance Description captures the information related to this unit of work. Systems built based on this specification can provide a holistic view of an activity, for example for monitoring, auditing or checkpointing purposes. The specification pursues two different but complementary objectives: (i) it specifies a generic and extensible framework to capture the information related to an activity; and (ii) it specializes this generic framework using a number of Open Grid Forum specifications.

This document specifies the procedure to create Uniform Resource Names (URNs) in the urn:ogf:network namespace. URNs in this namespace can be used to define logical network resources, such a devices, (logical) ports, (logical) links, and topologies.

In this document the EU-project European Middleware Initiative (EMI) describes a storage accounting record (StAR), defined to reflect practical, financial and legal requirements of storage location, usage and space and data flow. The defined record might be the base for a standardized schema or an extension of an existing record like the OGF UR and this document is intended as information to be taken as input for incorporating storage resources into the OGF UR.

Data resources play a significant role in many applications across multiple domains. Web services provide implementation neutral facilities for describing, invoking and orchestrating collections of networked resources. The OGF (Open Grid Forum) Open Grid Services Architecture (OGSA), and its associated specifications, define consistent interfaces through web services to components of the grid infrastructure. Both the web and grid communities stand to benefit from the provision of consistent and agreed web service interfaces for data resources and the systems that manage them.
This document presents a specification for a collection of querying interfaces for RDF(S) data resources, which extends interfaces defined in the Web Services Data Access and Integration document [WS-DAI]. It also presents interfaces for handling RDF graphs in RDF(S) data resources. This specification can be applied in regular web services environments or as part of a grid fabric.

This document describes the C language binding for the Distributed Resource Management Application API Version 2 (DRMAA). The intended audience for this specification are DRMAA Version 2 interface implementors.

This document provides a set of DFDL properties that can be used as defaults for creating DFDL schema.
