Metadb is a new streaming data integration platform that will eventually replace the Library Data Platform (LDP 1.x) software used by FOLIO project participants for reporting on FOLIO data. Metadb is still under development. Some institutions are running early versions of Metadb for testing purposes. The Cornell Library is currently running LDP 1.x on its production reporting database to provide users with access to FOLIO data for reporting. 

Data updates

The LDP software provides reporting users with a copy of yesterday's data from the FOLIO application server. Metadb will provide continuously streaming data updates from the FOLIO application server. This will provide reporting users with access to FOLIO data in near real time instead of yesterday's data. While LDP 1.x's architecture is limited to running on a single node, Metadb's architecture is horizontal, allowing for linear scaling of data updates. This allows updates to run in parallel within a single Metadb cluster.

...

Building report queries using the LDP software requires extracting some of the data from data arrays. By design, Metadb tables have data arrays broken out into columns, making it easier for query developers to use.

Special Features

Both LDP 1.x and Metadb include special features of interest to library reporting users: ldpmarc marct and the LDP Reporting app.

• Having access to MARC data is essential for Cornell Library reporting users. The ldpmarc marct tool currently converts SRS/MARC records from JSON to a tabular format for LDP 1.x and will be ported to support Metadb.
• The LDP Reporting app provides a FOLIO interface for interacting with an LDP or Metadb database. The Query builder in the LDP Reporting app allows you to build a simple query without using SQL with the option to save it for later use. The LDP App is currently available for LDP 1.x and will be included in Metadb in the future.
