Storing Metadata in a Table-based Format from Metadata in a Serial Format

摘要

In one embodiment, a method receives a document including metadata in a serial format and parses the document to determine components in the metadata, a nested structure of the components, and an order of the components in the data. The metadata is stored in a table format where columns of the table define the nested structure of the components and the order of the components in the data. A query is received for the data. The method determines components from the metadata stored in the table format from the columns that satisfy the query where the components are determined based on the nested structure of the determined components and the order of the determined components from information in the columns of the table. A result for the query is output including the determined components based on the nested structure of the determined components and the order of the determined components.

1. A method comprising:
receiving, by a computing device, a document including metadata in a serial format; parsing, by the computing device, the document to determine components in the metadata, a nested structure of the components, and an order of the components in the data; storing, by the computing device, the metadata in a table format, wherein columns of the table define the nested structure of the components and the order of the components in the data; receiving, by the computing device, a query for the data; determining, by the computing device, components from the metadata stored in the table format from the columns of the table that satisfy the query, wherein the components are determined based on the nested structure of the determined components and the order of the determined components from information in the columns of the table; and outputting, by the computing device, a result for the query, the result including the determined components based on the nested structure of the determined components and the order of the determined components.
