In support of the Office of Government Commerce (OGC) Electronic Property Information Mapping System (e-PIMS), the UK government agency has produced a version 2.1 draft of the CECA Property Data Structures specification which defines the data required to be submitted by Central Civil Government departments to the OGC about their Civil Estate property occupations. The goal of the UML/XML specification, which covers requirements of the Civil Estate Co-ordination Agreement (CECA), is to support the transfer and interoperability of e-PIMS data based on e-Gif standards. It outlines a proposed XML schema architecture for representing CECA Property data structures. This architecture has been developed with modular structure and has two clearly defined parts. The actual data structures referred to as the architecture and a set of schemas to be used to transfer the data, referred to as messaging schemas." This initiative is being developed "in line with the government's own e-Gif standards, but is essentially designed for use within the public sector, to facilitate the improvement in quality and accuracy of Civil Estate data. XML is being used extensively within the e-Government initiative to facilitate communication, with this in mind CECA is utilising XML as the key data format for bulk data transfer."

The CECA XML Specification will "facilitate the transfer of CORE CECA data between the database managed by OGC and other Estate Management databases managed by individual departments... This XML initiative is directed toward the support of the Core element of the CECA agreement and the implementation of linkages between government departments for the sharing of Civil Estate data. Core data is defined as specific information about individual properties (e.g., address, number of floors etc) which departments are required to provide to OGC..."

Address schema for CECA v2.1: "Currently in the CECAAddressStructure schema, the bs7666 schema is being referenced as follows: <xsd:schema targetNamespace="http://www.property.gov.uk" xmlns="http://www.property.gov.uk" xmlns:bs7666="http://www.property.gov.uk/schemas/bs7666/BS7666Schema.xsd xmlns:xsd="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified" version="2.0" id="CECAAddressStructure"> <xsd:import namespace="http://www.property.gov.uk/schemas/bs7666/BS7666Schema.xsd" schemaLocation=" http://www.property.gov.uk/schemas/bs7666/BS7666Schema.xsd "/>. This reference is based on a draft version of the BS7666 schemas which has not yet been published to a central schema repository. A version of the schema has been derived from the document UK Online - Information Architecture - BS7666 Address and Geographic Location Structures Fragment version 0.1c and dated 17th July 2001. This version has been published to a temporary repository at http://www.property.gov.uk/schemas/bs7666/BS7666Schema.xsd until the schema has passed through RFC and is made available through Govtalk...

UK e-PIMS: "The UK Office of Government Commerce (OGC) has developed an Electronic Property Information Mapping System (e-PIMS) for the government's civil property occupations... e-PIMS displays the precise location and outline of department's properties, holdings and occupations on computerised maps and will allow users to access and amend their own core property details on-line... It offers a sophisticated searching facility of all civil property occupations and displays detailed information in textual form. The system enables users to locate Individual properties on the electronic map and interrogate e-PIMS, for example to identify available vacant space. The technology allows the parameters of each search to be tailored to meet the individual needs of the user and provides digitised pictures of occupations..." [main e-PIMS web site]
