Convert XML JATS to PPM

The Journal Article Tag Suite (JATS) XML file extension is pivotal in digital publishing. XML stands for Extensible Markup Language. JATS, an NISO standard, was designed to tag and structure the content of scholarly articles. Initially derived from NLM (National Library of Medicine) DTDs in the early 2000s, JATS ensures consistent formatting and metadata tagging for articles, facilitating efficient indexing, searchability, and interoperability across various databases and platforms. Its use in the academic and scientific community supports robust archiving and seamless dissemination of knowledge.

The Portable Pixmap (PPM) file extension, an image format within the Netpbm family, stores simple, uncompressed images. Introduced in the late 1980s, PPM supports RGB color and grayscale images, making it suitable for basic image processing and conversion tasks. Its plain text encoding simplifies debugging and data manipulation, although its lack of compression results in larger file sizes compared to modern formats. As such, PPM finds limited use in contemporary applications, mainly in educational and experimental settings where ease of implementation and readability are prioritized.
