This schema is specified in IEEE P1636.2/D5.1, "Draft Trial-Use Standard for Software Interface for Maintenance Information Collection and Analysis (SIMICA): Exchanging Maintenance Action Information (MAI) via the Extensible Markup Language (XML)." This schema is a World Wide Web Consortium (W3C) Extensible Markup Language (XML) binding of the "SimicaCommon" component defined in IEEE P1636.2/D5.1. The purpose of this schema is to allow the creation of IEEE P1636.2/D5.1 instance documents.This schema uses the W3C XML Schema definition language as the encoding. This allows for interoperability and the exchange of SIMICA component instances between various systems. This schema shall not be modified but may be included in derivative works.

USE AT YOUR OWN RISK Base type for any element that will contain information to identify a hardware item Properties: isRef 0, content complex The HardwareInstance/Calibration child element shall contain the date and time the hardware item was last calibrated. The date and time of the last calibration Properties: isRef 0, content complex The HardwareInstance/Components child element shall identify the next-lower assembly(s) belonging to the parent hardware item. Base type: c:ItemInstanceReference Properties: isRef 0, content complex The HardwareInstance/Components/Component child element shall identify each next-lower assembly(s) belonging to the parent hardware item. Base type: c:HardwareInstance Properties: isRef 0, content complex The HardwareInstance/ParentComponent child element shall identify the next-higher assembly to which the parent hardware item belongs. Properties: isRef 0, content complex The HardwareInstance/PowerOn child element shall indicate the number of power-on cycles and the total power-on time experienced by the hardware item at the time of creation of the XML instance document. The number of power on/off cycles experienced by the hardware item at the time of record creation. This information may be useful in applications where diagnostics are performed. The total cumulative time that power has been applied to the described hardware item. This information may be useful in applications where diagnostics are performed. Base type for any element that needs to be identified This attribute is used to store the identification number text. This attribute is used to identify the type of identification number. Identifies the name of the manufacturer. Provides additional descriptive data that further specifies or identifies the Identification Number. Base type for any element that will contain information to identify a software item Base type: xs:date Properties: isRef 0, content simple The SoftwareInstance/ReleaseDate child element shall contain the actual release date of the referenced software item. Base type for any element describing an instance The date the item was issued as available for use. Identifies the warranty associated with an Instance of an System Base type for any element that require an element to reference an sc:SystemInstance which has no serial number. Identifies the UUID corresponding to the specific instance document. Uniquely identify a specific description of a system. Base type for any element defining identifying information for the item being maintained The identifier for the document or collection of information across multiple levels of maintenance. The identifier for the document or collection of information at a level of maintenance. Contains information regarding the level of maintenance. The abbreviation for the level of maintenance. The name of the level of maintenance. The description of the maintenance action task. Element provided to permit extensibility of the schema. Base type for any element defining a manufacturer's legal responsibility for the support of a given system or item Name of the manufacturer which warrants the unit Time the unit is covered by the warranty, e.g. one-year warranty, two-year warranty, etc. Date when the manufacturer warranty begins to take effect Discrepancy in the unit that is not covered by the warranty
