POMELo: A PML Online Editor

This paper introduces POMELo, a simple, web-based PML (Proof Markup Language) editor. The objective of POMELo is to allow users to create, edit, validate and export provenance information in the form of PML documents. This application was developed with provenance novices in mind, making it usable in various settings, from educational to scientific. Since this is a web-based application, users do not need to install or run any software aside from a normal web browser, which simplifies its adoption and makes it more attractive for inexperienced users.
