详细说明： 1 Scope This standard defines an octet-level data encoding protocol for representing data items and data groups. This protocol defines a data structure which is inde- pendent of the application or transportation method used. The standard defines a key-length-value (KLV) triplet as a data interchange protocol for data items where the key identifies the data, the length specifies the length of the data, and the value is the data itself. The KLV protocol provides a common interchange for all compliant applications irrespective of the method of implementation or transport. The standard also provides methods for combining associated KLV triplets in data sets where the set of KLV triplets is itself coded with KLV data coding pro- tocol. Such sets can be coded in either full form (universal sets) or in one of four increasingly bit-effi- cient forms (global sets, local sets, variable-length packs, and fixed-length packs). The standard pro- vides a definition of each of these data constructs. The encoding octet range (length of the payload) specified in this standard may generate unusually large volumes of data. Consequently, a specific appli- cation of KLV encoding is capable of only a limited operating data range and those details shall be de- fined in a relevant application document. ...展开收缩
