3 Terms and Definitions

The following terms and definitions defined in GB/T.20000.1 apply to this document.

4 Consistency check content

4.1 Integrity Check Integrity checks for publication digital content objects and their associated resource data include. a) Integrity check of the logical structure of the object model. whether the object model fully expresses the semantic relationship of the digital content objects of the publication, the object Whether the instance is complete, and whether the object instance is complete including mandatory attributes, etc.; b) Information package integrity check. check the existence of the necessary files (and file directories) in the object instance information package. 4.2 Compliance check Compliance checks for publication digital content objects and their associated resource data include. a) Object semantic conformity check. whether the object model conforms to constraints, check of inference rules, etc.; b) Information package compliance check. Whether the semantic relationship in the PUBO RDF instance file is consistent with the information package list file (ie pubomanifest.xml file) in the object relationship list (that is, the content under the node objectList); PUBO RDF Whether the media objects and their physical files in the instance file are consistent with the list of data files in the information package manifest file (that is, the node content under dataFileList) match. 4.3 Validity check Validity checks for publication digital content objects and their associated resource data include. a) Object model logic validity check. check the value validity of attributes, etc.; b) Grammatical validity check. check whether it conforms to XML, RDF, OWL related grammars, etc. 4.4 Accuracy Check The accuracy check of the publication digital content object and its related resource data is mainly to check the content of the object instance information package, Including directory name and location in the file system, file name and location, location of container.xml and pubomanifest.xml files Is it accurate etc.

5 Consistency check method

5.1 Semantic Checking Method With the semantic check method, you can override checks for. -- Integrity check of the logical structure of the object model; -- Object semantic conformity check; -- Object model logic validity check; -- Syntax validity check. The specific method of semantic checking is as follows. a) Object model logical structure inspection. the inspection object is PUBO and its extension model. The content of the check is the semantics of the logical structure of the ontology Consistency. The check of the logical structure can be completed through the ontology model definition file and the corresponding ontology inference engine; b) Instance data logic structure inspection. the inspection object is RDF instance data conforming to PUBO or its extended model. Check content includes Whether it conforms to the logical structure of the ontology model; for the attributes of the instance, the inspection content includes attributes and inverse attributes, transitive attributes, symmetry properties, etc. The logical structure can be checked through RDF instance data files, ontology model definition files and corresponding The ontology reasoning machine is completed; c) Constraint check. the check object is RDF instance data. Check content includes cardinality constraint check and value constraint check. PUBO See Appendices A.1, A.2 and A.3 for examples of cardinality constraints. In the extension model of PUBO, it is necessary to limit the scope of the extended derived class When determining the value of an attribute, the check of the value constraint should be considered. Constraint checking can be done through the ontology model definition file and the corresponding The ontology reasoning machine is completed; d) Special constraint check. the check object is RDF instance data. The inspection content includes pre-defined term value inspection, attribute consistency Sexual relationship check. See 6.1 and 6.2 for inspection methods. Examples of special constraints in PUBO can be found in Appendices A.4 and A.5. 5.2 Packet Authentication Method With the packet authentication method, you can override checks for. -- Packet integrity check; -- Packet compliance check; -- Packet accuracy check. The specific method of packet verification is as follows. The information package of the Publication Digital Content Object mainly includes PUBO RDF instance files and a set of related data files. packets according to A certain structure to organize files. For data files, use the validation provided by the "validation algorithm" and "validation value" properties in the object model information to ensure that the content of the data file is effectively verified. The verification of the information packet includes the verification of the information packet structure (see 7.1), the data file Validation (see 7.2) and object instance relationship validation (see 7.3) and other three aspects.

6 Special Constraint Checks

6.1 Predefined term value check In the PUBO extension system, coding systems such as vocabulary and taxonomy can be defined by instantiation of "predefined terminology sets". Using the "pre- The instance of "definition term" represents information such as specific glossary vocabulary, taxonomy vocabulary or classification symbols. In the process of verifying the instance data, it is necessary to check whether the value of the predefined term matches the matching predefined term set. 6.2 Attribute consistency check 6.2.1 Attribute Consistency Relationship Types All kinds of resources described by PUBO have a variety of attributes, and there is a certain relationship between the attributes. The types include. a) Attribute coexistence relationship. For an instance, two or more attribute values must exist, or none exist; b) Attribute same-value relationship. For two different instances, the value of one or two attributes must be the same. If the title of a series of books is related to the The series title must be the same for an individual book in a series. 6.2.2 Attribute coexistence check See Table 1 for attribute coexistence relationship checking rules, and see Appendix A.4 for examples. 6.2.3 Attribute equality check See Table 2 for attribute equivalence check rules, and see Appendix A.5 for examples.

7 Object Packet Authentication

The data files that pass the verification can be exchanged and received correctly, and used for long-term storage and inspection See Table 20 for methods. 7.2.3 Data file redundancy check According to the actual situation of the data files in the information package, check whether it is redundant. The verification method is shown in Table 21. 7.3 Object Instance Relationship Validation According to the object instance in the PUBO RDF instance file and the value of the object attribute, the relationship with the object instance in pubomanifest.xml Compare the item information in the list (objectList). Verify its consistency, the verification method is shown in Table 22.
