SISO-STD-001-1999: Guidance, Rationale, & Interoperability Modalities for the RPR FOM (GRIM 1.0)
This document was created as a community effort by the Real-time Platform Reference Federation Object Model (RPR FOM) Standards Development Group (SDG). This SDG was chartered by the Simulation Interoperability Standards Organization's Standards Activity Committee on May 19, 1998.

SISO-STD-001.1-1999: Real-time Platform Reference Federation Object Model (RPR FOM 1.0)
Common Foundation Reference FOM (CF-RFOM) as defined by the SISO Reference FOM Study Group (see Simulation Interoperability Standards Organization, "Reference FOM Study Group Final Report," Version 1.0, March 9, 1998).

SISO-STD-002-2006: Standard for: Link16 Simulations (approved 10 Jul 06)
There are immediate operational requirements for existing military simulations to exchange Link 16 data using a single interoperable standard. Several protocols have evolved to satisfy specific needs. The NATO STANAG 5602 Standard Interface for Multiple Platform Link Evaluation (SIMPLE) Link 16 standard (Reference 8) is one such protocol. As military distributed simulation evolves further in mission scale and complexity, tactical datalink
implementations need to interoperate.

SISO-STD-003-2006: Base Object Model (BOM) Template Specification (approved 8 May 06)
The “Base Object Model (BOM) Template Specification” defines the format and syntax for describing the elements of a template for representing BOMs. It specifies the semantics of the elements of a BOM and the syntax for constructing BOMs from those elements. In addition, this specification provides a data interchange format (DIF) for the representation of BOMs using the Extensible Markup Language (XML). The BOM DIF enables tools to exchange and reason about BOMs.

SISO-STD-003.1-2006: Guide for BOM Use and Implementation (approved 8 May 06)
This “Guide for Base Object Model (BOM) Use and Implementation” introduces methodologies for creating BOMs and implementing them in the context of a larger simulation environment. The document is a means of familiarizing the reader with the concept of BOMs and providing guidance for BOM development, integration, and use in supporting simulation development.

SISO-STD-004-2004: Dynamic Link Compatible HLA API Standard for the HLA Interface Specification Version 1.3
Compliance with the application programmer interfaces defined in this specification will permit simulation developers to interchange link compatible HLA RTIs without recompiling federate source code or re-linking federate object code with Dynamic Link-Compatible (DLC) RTI libraries. The use of DLC compliant RTIs does not ensure that federations will have similar performance, but will enable federate developers to easily utilize RTIs provided by different vendors.

SISO-STD-004.1-2004: Dynamic Link Compatible HLA API Standard for the HLA Interface Specification (IEEE 1516.1 Version). (Includes a zip file of class headers).
Compliance with the application programmer interfaces defined in this specification will permit simulation developers to interchange link compatible HLA RTIs without recompiling federate source code or re-linking federate object code with Dynamic Link-Compatible (DLC) RTI libraries. The use of DLC compliant RTIs does not ensure that federations will have similar performance, but will enable federate developers to easily utilize RTIs provided by different vendors that support this objective.

SISO-STD-006-2010: Commercial Off-the-Shelf (COTS) Simulation Package Interoperability (CSPI) Reference Models
This "Standard for COTS Simulation Package Interoperability Reference Models" introduces a set of templates or patterns intended to classify specific interoperability problems encountered in the development of distributed simulations consisting of CSPs and their models. The purpose is to form a common ground where the capabilities of current approaches to CSP interoperability/distributed simulation can be assessed and compared and where practitioners, CSP vendors and solution developers can identify candidate solutions to their interoperability/distributed simulation problems.

SISO-STD-007-2008: Military Scenario Definition Language (MSDL) (approved 14 Oct 08)
MSDL is defined using an XML schema. Compliance with the MSDL XML schema defined in this specification will permit simulations to generate military scenarios where each scenario consists of either the initial state or a state snapshot.   Future versions of the standard are expected to include additional organizational structures, electronic order of battle information, targeting information, and data structures to hold the planned activities of the organizations and entities defined within the scenario.

SISO-STD-008-2010: Core Manufacturing Simulation Data (CMSD)
This product defines a data interface specification for efficient exchange of manufacturing life cycle data in a simulation environment. The specification provides neutral data interfaces for integrating manufacturing software applications with simulation systems.
