Apparatus and method for template driven data extraction in a semi-structured document database

An apparatus, comprising:

• a processor implemented by hardware;
• and
• a memory connected to the processor, the memory storing instructions executed by the processor to:
• ingest and store a semi-structured document within a database;
• suggest a template based upon an evaluation of the semi-structured document, wherein
• the template includes a context specification defining a template context that corresponds to a context within the semi-structured document, and
• the template further includes an index specification characterizing data to be extracted from the semi-structured document;
• receive a template selection of the suggested template;
• execute the template selection to form an index entry of a respective query format for the semi-structured document within an index, of the database, that supports multiple query formats, including relational query format and triple (subject-predicate-object) query format;
• receive a query in at least one of the multiple query formats;
• and
• resolve the query in the at least one of the multiple query formats against the index.
