Glossary of Terms - I

image metadata
XML encoding used to describe all types of images handled by OpenGIS Framework services. Image Metadata is used for publishing and discovery of types of original and derived images, image identifications, dates, spatial extents and other information that could be used to find and retrieve images from an archive.
A common way of collecting information associated with a coverage, by which the value of a continuous phenomenon is usually sampled at regular but discrete locations, i.e. pixels.
A software package that conforms to a standard or specification. A specific instance of a more generally defined system.
implementation profile
An Implementation Profile contains an interoperable set of implementation technologies. The languages and associated technologies that a functioning enterprise depends upon are part of the Implementation Profiles for an environment. In addition to modeling languages, Implementation Profiles contain inter-process communication protocols and other dependent infrastructure technologies that the framework employs.
implementation specification
Guidance for software engineers that is so specific that any two independent software implementations of the specification can "plug and play" for each other.
implementation view
Part of Information Viewpoint that captures how information must be represented within a working enterprise (i.e., how it is encoded for runtime use).
information appliance
End-user equipment having input and display (or auditory) capabilities for communication with other users or service providers in the NII.
Information Community
Source: The OpenGIS® Abstract Specification Topic 6: The Coverage Type and its Subtypes Version 6. A collection of people (a government agency or group of agencies, a profession, a group of researchers in the same discipline, corporate partners cooperating on a project, etc.) who, at least part of the time, share a common digital geographic information language and common spatial feature definitions. See Topic 14, Semantics and Information Communities.
Information Storage Interface (ISI)
The interface across which information technology interacts with external storage media. The service provided through this interface is persistent storage of data, where the physical storage media is often removable.
integrated client
A software application that provides a unified environment for visualizing, analyzing, and editing geospatial data from a wide variety of sources.
A named set of operations that characterize the behavior of an entity. An implementation of operations including the syntax of the interaction for a given distributed computing technology. A shared boundary between two functional entities. An established ordering of parameters (with specific names and data types) and instructions (with specific names and functions) that enables one software component to exchange data and instructions with another software component.
A service that provides functions by which to interconnect, adapt and facilitate services offered by other parties, components or environments. Common forms of intermediaries include agent, broker, mediator and trader services.

Capability to communicate, execute programs, or transfer data among various functional units in a manner that requires the user to have little or no knowledge of the unique characteristics of those units ISO 2382-1. "The ability for a system or components of a system to provide information portability and interapplication, cooperative process control. Interoperability, in the context of the OpenGIS Specification, is software components operating reciprocally (working with each other) to overcome tedious batch conversion tasks, import/export obstacles, and distributed resource access barriers imposed by heterogeneous processing environments and heterogeneous data. "
Interoperability Program
The OGC Interoperability Program is a global, collaborative, hands-on engineering and testing program designed to deliver proven candidate specifications into the OGC Specification Development Program and to exercise and test existing OGC Implementation Specifications in domain specific situations.
Interoperability Program Report (IPR)
An IPR is provided by an Interoperability Program Initiative to the TC. IPR documents may be submitted to the OGC TC for review and comment. Depending on the desired outcome, the document type should be either "Information-Only", "Draft Discussion Paper", "Draft Recommendation Paper", or "RFC Proposal". The first, obviously, is intended for information only and is not to be considered for public release. The second approach is intended for consideration for public release as a Discussion Paper. The third is intended for consideration for public release as a Recommendation Paper. The last is intended for consideration as an RFC proposal (and must be submitted under the TC Policies and Procedures for RFCs). An IPR is not a publicly available document. An IPR will be provided to the TC in the correct IPR template format. An IPR does not represent the official position of the OGC nor of the OGC Technical Committee.
intrinsic resource
A registered resource for which the content model and normative representation are defined by the Registry Information Model (RIM).
