5. The method of claim 3, wherein populating the XAPI declaration with event values in each learning event in the SCORM standard data, comprising:
and filling event values in each learning event in the SCORM standard data into variables in a data structure corresponding to the XAPI statement.
6. The method of any of claims 1-5, wherein obtaining the score standard data to be converted comprises:
responding to a playing request of the SCORM standard data, and acquiring the SCORM standard data;
after obtaining the XAPI standard data corresponding to the SCORM standard data, the method further comprises:
and playing the XAPI standard data by using a playing plug-in based on the XAPI standard.
7. A data conversion apparatus, comprising:
the data acquisition module is used for acquiring SCORM standard data to be converted, wherein the SCORM standard data comprises at least one learning event, and the learning event comprises: event description information and event values;
the statement acquisition module is used for acquiring the XAPI statement corresponding to each learning event in the SCORM standard data according to the event description information and the mapping relation between the SCORM standard and the XAPI standard;
the data conversion module is used for correspondingly filling event values in all learning events in the SCORM standard data into the XAPI statement to obtain XAPI standard data corresponding to the SCORM standard data;
wherein, still include: the mapping relation establishing module is used for traversing event verbs in a data model of the SCORM standard before acquiring SCORM standard data to be converted, and registering the event verbs in a declarative verb list of the XAPI standard;
traversing event operation objects in a data model of the SCORM standard, and registering the event operation objects in a statement object list of the XAPI standard;
traversing the data model in the SCORM standard, and acquiring all event description information corresponding to the data model in the SCORM standard;
