Core architecture data model (CADM) is designed to capture DoDAF architecture information in a standardized structure. CADM was developed to support the data requirements of the DoDAF. The CADM defines the entities and relationships for DoDAF architecture data elements that enable integration within and across architecture descriptions. In this manner, the CADM supports the exchange of architecture information among mission areas, components, and federal and coalition partners, thus facilitating the data interoperability of architectures.

The DoDAF v1.5 was an evolution of the DoDAF v1.0 and reflects and leverages the experience that the DoD components have gained in developing and using architecture descriptions. This transitional version provided additional guidance on how to reflect net- centric concepts within architecture descriptions, includes information on architecture data management and federating architectures through the department, and incorporates the pre-release CADM v1.5, a simplified model of previous CADM versions that includes net-centric elements. Pre-release CADM v1.5 is also backward compatible with previous CADM versions.

Data sets built in accordance with the vocabulary of CADM v1.02/1.03 can be expressed faithfully and completely using the constructs of CADM v1.5. Note: For DoDAF V2.0, The DoDAF Meta-model (DM2) is working to replace the core architecture data model (CADM) which supported previous versions of the DoDAF. DM2 is a data construct that facilitates reader understanding of the use of data within an architecture document. CADM can continue to be used in support of architectures created in previous versions of DoDAF.

Conformance with the CADM ensures the use of common architecture data elements (or types).

CADM is a critical aspect of being able to integrate architectures in conformance with DoDAF. This includes the use of common data element definitions, semantics, and data structure for all architecture description entities or objects. The use of the underlying CADM faithfully relates common objects across multiple views. Adherence with the framework, which includes conformance with the currently approved version of CADM, provides both a common approach for developing architectures and a basic foundation for relating architectures.

The CADM was initially published in 1997 as a logical data model for architecture data. It was revised in 1998 to meet all the requirements of the C4ISR Architecture Framework Version 2.0.1 As a logical data model, the initial CADM provided a conceptual view of how architecture information is organized. It identified and defined entities, attributes, and relations. The CADM has evolved since 1998, so that it now has a physical view providing the data types, abbreviated physical names, and domain values that are needed for a database implementation.

Because the CADM is also a physical data model, it constitutes a database design and can be used to automatically generate databases. The CADM v1.01 was released with the DoD Architecture Framework v1.0 in August 2003. This DoDAF version restructured the C4ISR Framework v2.0 to offer guidance, product descriptions, and supplementary information in two volumes and a desk book.

It broadened the applicability of architecture tenets and practices to all mission areas rather than just the C4ISR community. This document addressed usage, integrated architectures, DoD and Federal policies, value of architecture, architecture measures, DoD decision support processes, development techniques, analytical techniques, and the CADM v1.01, and moved towards a repository-based approach by placing emphasis on architecture data elements that comprise architecture products.DoD (2007). DoD Architecture Framework Version 1.5 Volume 1. 23 April 2007 The CADM v1.5 was pre-released with the DoD Architecture Framework, v1.5 in April 2007.

The counterpart to CADM within NASA is the NASA Exploration Information Ontology Model (NeXIOM), which is designed to capture and expressively describe the engineering and programmatic data that drives exploration program decisions. NeXIOM is intended to be a repository that can be accessed by various simulation tools and models that need to exchange information and data.Robert Shishko (2004). The Application of Architecture Frameworks to Modelling Exploration Operations Costs .

CADM Data Model Diagram Notation. As illustrated in the figure, boxes represent entities for which architecture data are collected (representing tables when used for a relational database); they are depicted by open boxes with square corners (independent entities) or rounded corners (dependent entities). The entity name is outside and on top of the open box. The lines of text inside the box denote the attributes of that entity (representing columns in the entity table when used for a relational database).

In February 2004 the documentation of Version 1.0 was released with volume "I: Definitions and Guidelines", "II: Product Descriptions" and a "Deskbook". In April 2007 the Version 1.5 was released with a documentation of "Definitions and Guidelines", "Product Descriptions" and "Architecture Data Description".

To correct this inequity, the rank of commodore as a single star flag officer was reinstated by both services in the early 1980s. This immediately caused confusion with those senior U.S. Navy captains commanding destroyer squadrons, submarine squadrons, functional air wings and air groups, and so on, who held the temporary "title" of commodore while in their major command billet. As a result of this confusion, the services soon renamed the new one-star rank as commodore admiral (CADM) within the first six months following the rank's reintroduction. However, this was considered an awkward title and the one-star flag rank was renamed a few months later to its current title of rear admiral (lower half), later abbreviated by the U.S. Navy and U.S. Coast Guard as RDML.

DoDAF has a meta-model underpinning the framework, defining the types of modelling elements that can be used in each view and the relationships between them. DoDAF versions 1.0 thru 1.5 used the CADM meta-model, which was defined in IDEF1X (then later in UML) with an XML Schema derived from the resulting relational database. From version 2.0, DoDAF has adopted the IDEAS Group foundation ontology as the basis for its new meta-model. This new meta- model is called "DM2"; an acronym for "DoDAF Meta-Model". Each of these three levels of the DM2 is important to a particular viewer of Departmental processes: #The conceptual level or Conceptual Data Model (CDM) defines the high-level data constructs from which Architectural Descriptions are created in non-technical terms, so that executives and managers at all levels can understand the data basis of Architectural Description.

Synaptic cell adhesion molecules (CAMs) play a crucial role in axon pathfinding and synaptic establishment between neurons during neurodevelopment and are integral members in many synaptic processes including the correct alignment of pre- and post-synaptic signal transduction pathways, vesicular recycling in regards to endocytosis and exocytosis, integration of postsynaptic receptors and anchoring to the cytoskeleton to ensure stability of synaptic components SynCAM’s (also known as Cadm or nectin-like molecules) are a specific type of synaptic CAM found in vertebrates that promotes growth and stabilization of excitatory (not inhibitory) synapses. SynCAM’s are localized primarily in the brain at both pre- and postsynaptic sites and their structures consist of intracellular FERM and PDZ binding domains, a single transmembrane domain, and three extracellular Ig-domains. During neurodevelopment, SynCAMs such as SynCAM1 act as “contact sensors” of axonal growth cones accumulating rapidly when axo-dendritic connections are made and helping to form a stable adhesion complex. synCAM1 along with neuroligin are the two CAM’s known to be sufficient to initiate the formation of presynaptic terminals, as addition of synCAM1 to media of co-cultured neuronal and non- neuronal cells lead to the establishment of presynaptic terminals.
