The term spatial data infrastructure was coined in 1993 by the U.S. National Research Council to denote a framework of technologies, policies, and institutional arrangements that together facilitate the creation, exchange, and use of geospatial data and related information resources across an information-sharing community. Such a framework can be
implemented narrowly to enable the sharing of geospatial information within an organization or more broadly for use at a national, regional, or global level. In all cases, an SDI will provide an institutionally sanctioned, automated means for posting, discovering, evaluating, and exchanging geospatial information by participating information producers and users. SDI extends a GIS by ensuring geospatial data and standards are used to create authoritative datasets and polices that support it...

...ArcGIS for INSPIRE helps meet INSPIRE compliance in a timely manner by extending the ArcGIS software that already exists in your organization...

Hence, the basic software components of an SDI are:
1. a software client - to display, query, and analyse spatial data (this could be a browser or a Desktop GIS),
2. a catalogue service - for the discovery, browsing, and querying of metadata or spatial services, spatial datasets and other resources,
3. a spatial data service - allowing the delivery of the data via the Internet,
4. processing services - such as datum and projection transformations,
5. a (spatial) data repository - to store data, e.g. a Spatial database,
6. GIS software (client or desktop) - to create and update spatial data.
