The BIDM consists of five classes that each have a set of attributes and relationships. An attribute is a field that contains textual data. A relationship is field that is used to relate one class to another class. In the context of RIB, the value of a relationship is a URL. RIGObject is the root class of the BIDM model. The "Name" attribute defined in the RIGObject class is inherited by all subclasses. The four BIDM subclasses along with their attributes and relationships are described below. Relationships are denoted by an asterik ( * ). For a graphical depiction of the data model, see Figure 1 below.
The BIDM standards document (IEEE Standard 1420.1) may be purchased by contacting the IEEE at 1-800-678-IEEE or by visiting their website at http://standards.ieee.org/. The standard was developed as a collaboration between the Reuse Library Interoperability Group (RIG) and the Software Engineering Standards Committee (SESC) of the IEEE Computer Society, which has since evolved into the Reuse Steering Committee (RSC). |
Extensions to the BIDMStandard NHSE extension While using the BIDM within the National HPCC Software Exchange (NHSE), several fields in addition to the standard BIDM fields were found to be useful. Those fields are included in the standard NHSE extension. The fields are :
Asset Certification Framework The Asset Certification Framework (ACF) extension to the BIDM is an IEEE standard (1420.1a) that includes additional classes for information about Asset Certification, also called software review or evaluation. See Figure 2 below for a graphical depiction os the ACF. These additional classes can be used by reuse libraries to describe their certification policies and to exchange certification metadata. Intellectual Property Rights Framework The Intellectual Property Rights Framework (IPRF) extension to the BIDM is an IEEE standard (1420.1b) that includes additional classes for information about the rights management policies for a reuse library. See Figure 3 below for a graphical depiction os the IPRF. These additional classes allow reuse libraries to provide a basis for understanding what rights are attached to a particular asset and what restricitions are placed on the reuser. NHSE Deployment The NHSE Deployment extension includes classes which can be used to describe the deployment (installation) status of Assets. It includes to new classes - Machine, and Deployment. The Deployment class contains the relationships DeployedOn.Machine and IsDeploymentOf.Asset which can be used by RIB to create joins. Click here for more information about joins. |

Simplified BIDMThe simplified BIDM is a heavily scaled down version of the full BIDM described above. It is intended for new or "lightweight" users of RIB who want to use the RIB interface without having to worry about satisfying all the conditions of a strict data model. It contains only two classes from the full BIDM - Asset and Organization. Several of the attributes and relationships that are required in the full BIDM are not required in the simplified version.The extensions to the BIDM that are described above cannot be used with the simplified BIDM because it doesn't support all of the core BIDM classes. Interoperation is possible with the simplified BIDM, but not as robust or scalable as using the full BIDM. |
Address - in Organization, the mailing address of the organization (or person). Includes street number, name, city, state, zipcode, and count ry. Assigns - relates a RightsCategory(s) to a RightsAssessment. A rights assessment assigns to the Asset a particular category of accessibility (e.g., Shareware) Attribute - a characteristic of a class for which a value may be gi ven for an instance of that class. Asset - any reusable entity in the software life cycle process (e.g ., a software package, tool, or routine). AwardedWith - relates an asset to a certificate that states that th e asset has been assessed or evaluated according to specified evaluation c riteria. BIDM - Basic Interoperability Data Model Certificate - software review or evaluation. CertificationArtifact - a tangible result from a certification proc ess (e.g., inspection checklist, metric report). CertificationLevel - Certification level awarded to an asset by a c ertificate. CertificationMethod - the method applied in assessing a certificati on property (e.g., inspection, static analysis, testing, formal verificati on, benchmarking). CertificationPolicy - The policy used for the certification process of the Asset. CertificationProperty - A feature or characteristic of an asset tha t may be assessed during a certification process. CertificationStatus - status of the certificate (e.g., approved, re jected, in progress). CertifiedBy - indicates the organization that issued the certificat e or performed the certification process. Class - type of BIDM object ContactIs - An organization that is a point of contact for a librar y or asset (an organization can be a person). Copyright - a statement of copyright for the asset Cost - the type and amount of fees a subscriber must pay to obtain the right to reuse an asset, including type of currency paid and pricing p olicy for maintenance support and upgrades. DateOfInformation - the date the information about an asset was last updated. DefinedBy - relates a RightsCategory to a RightsPolicy. The governing rights policy of an organization determines the accessibility of the Asset and thus defines the rights category. Disclaimer - a statement of disclaimer for the asset DistributionStatement - an indication of who may receive an asset. Domain - a broad area of interest, application area, or area of act ivity or knowledge. Element - a file that is part of an asset ElementType - the kind of element (e.g., source code, test suite, m akefile) Field - an attribute or relationship. Icon - the url for an icon that graphically represents or provides information about the asset. IsComposedOf - indicates an asset that is a subset or part of an as set. IsLocatedIn - indicates a library (i.e., repository) in which an as set is located. IsMadeOf - indicates an element (i.e., file) that is part of an ass et. IsOwnedBy - relates an Asset to an Organization. Shows what organization(s) own the Asset determined by the rights assessment Keyword - a word or phrase that describes the asset. Language - programming language used to express one or more element s of an asset. Library - repository that contains assets. LicensingTerms - the terms of the license for the asset (via the Element) or rights category Local - found in the repository currently being administrated. Media - the media through which an element can be obtained (e.g., C d-ROM, electronic, etc.). Name - name or title of an object Non-local - found in another (foreign) repository. Object - an instance of a class. Organization - a person, company, research group, etc. that creates and manages an asset or library. Patent - a statement of a patent held on the asset or part of the asset PerformedBy - relates the rights assessment of an Asset to the Organization that is responsible for that assessment PolicyEffectiveDate - date the CertificationPolicy was made effecti ve for the organization. PolicyReference - reference to document(s) or standard(s) that defi ne a CertificationPolicy. PropertyDescription - a statement about some feature or characteris tic of an asset that may be assessed as being true or false during a certi fication process. RecordMaintainedBy - an organization (see Organization) that is res ponsible for maintaining the catalog record for an object. Relationship - a relationship between two classes, expressed by a l ink from an instance of the first class to an instance of the second. RestrictedBy - relates an Asset to a RightsAssessment that has been performed on that asset. Restrictions - legal information governing the use of the asset, in cluding possibly copyright, patents, data rights, disclaimers, export rest rictions, and licenses. RIB - Repository In a Box RIG - Reuse Library Interoperability Group RightsAssessment - a statement of the intellectual property rights of an asset (i.e. whether the asset is trademarked, patented, etc.) RightsCategory - a rights management (e.g., distribution) category defined by a RightsPolicy RightsPolicy - a statement of a reuse library's policy for rights management SecurityClassification - the highest security classification assign ed to the asset or to any part of it. TargetEnvironment - computer system, operating system, and/or compi ler for which an asset was developed or on which an asset will operate.

Trademark - a statement of trademark associated with the asset TradeSecret - a statement of trade secret associated with the asset UniqueID - a name or handle used to refer to the set of data that m akes up the identity of the asset or element. Version - the designation of the version of an asset (usually a num ber). VersionDate - the publication date for the given version of an asse t (i.e., the date the asset was made available for public use).
