The combination of METS and ALTO (often written METS/ALTO) is the current industry standard for newspaper digitization used by hundreds of modern, large-scale newspaper digitization projects

Benefits:

METS has the capability to support article segmentation, so articles, headlines, bylines, and other article-level metadata can be captured.
The combination of METS and ALTO captures very “rich” data, allowing the development of innovative discovery and delivery interfaces.
Both METS and ALTO are open XML standards — no proprietary software is required to read or transform the digitized objects.

Web Interface (Web based application):

A web-based application is any application that uses a website as the interface (the ‘front-end’). Users access the application from any computer connected to the Internet using a standard browser, instead of using an application that has been installed on their local computer.
