Copyright (C) 2008-2010, Cable Television Laboratories, Inc. SaFI Common Release Candidate XML Schema Version 1.1.-1 Derivative ID type. This can be a GUID represented in RFC 4122 Base64-URL form (so 16 bytes convert to a 22 byte string). This might use a more terse form, but some namespace resolution is needed first. Enhancement sequence number within a Programmed Element. These sequence numbers are assigned to message-addressable nodes in the campaign description associated with UUIDs and ETypes. The UUID+EPSID can be used to locate the node and its ETYPE allows further navigation. Limited to 2 binary bytes. EventID uniquely identifies each component or event in the application such as overlay, poll question, RFI, etc.. This is an xs:string restricted to have some actual content This is an xs:int restricted to zero or positive content Programmed Element ID type. Initially this is a GUID represented in RFC 4122 Base64-URL form (so 16 bytes convert to a 22 byte string). This might use a more terse form, but some namespace resolution is needed first. This is an xs:int restricted to positive content This identifies a complete application. It is a key to access the application characterization in the application repository. The attribute set for characterizing an application. The repositoryAppKey characterized an application according to the specification format, and the OrgID,AppID,version identify a specific expression of that repository template held in the application repository. AppId/orgId/appVer are a set, all present or absent. Either that set or appDataReverence or both must be present for the applicationDefinition to be valid. Note that appVer is to be deprecated in a future release. Use appVerMajor and appVerMinor. Attribute set that defines some instant, or interval starting at some instant. The instant is offset from some event, usually start of flight (as xs:duration), and the interval is a duration after the offset. Attribute set that may define some instant, or interval starting at some instant, but may also be empty. The instant is offset from some event, usually start of flight (as xs:duration), and the interval is a duration after the offset. A syscode is a unique human-readable identifier that tends to represent an insertion point (ex. splicer). These system level syscodes are at the MSO level within a given market. Larger network areas are represented by a syscode that is itself composed of syscodes. UUID is a 16 byte integer, encoded using RFC 4122 Base64-URL form, so encodes to ceiling((bytes)/3)*4 = 24 Base64 bytes less padding, so 22 total. It would be about 43 decimal, 32 hex digits. UserInput is a string used to store a user's selection to a poll, RFI, etc.. This element is optional as it will not be included in messages representing Service Metric updates. Parameters is an optional string block used to pass other relevant data Human-readable contact phone, so may have extension, etc. Not expected to be machine processable Major version provides the macro versioning number for each interface. Versions containing the same major version should provide backwards compatibility. The MinSchemaVersion should refer to a MajorVersion number. MinorVersion allows incremential and backwards compatible updates to be independently versioned. MicroVersion is negative ordinals starting at -1 for ReleaseCandidates, and non-negative ordinals starting at 0 for releases. Assumed to be zero if omitted. MinSchemaVersion is lowest compatible schema version number (assumes all forward compatible within MajorVersion) A document with a minSchemaVersion of 2 is compatible with any processor implementing schema version 2 or greater, but not with a processor implementing schema 1. MinSchemaMinorVersion is the lowest compatible schema minor version number. If missing, all minor version numbers are assumed to be compatible. Extensibility - elements from any namespace. GeographicCode is an identifier used to denote the location of the device/unit. This could be zipcode or syscode. Unique program identifier. Reference date and time. A name-value pair report data set A value from SCTE 35 Table 8-6 identifying the information format. The information length in bytes. Limits may be applied as per SCTE 35 Table 8-6. A 32-bit unique segmentation event identifier. The segmentation type as specified by SCTE 35 Table 8-7. Identification of a specific segment within a segmentation upid. Expected number of individual segments within the segmentation upid. Contextual reference date and time. Defines an absolute time range.
