# MaKR

MaKR (=**Ma**thematical **K**nowledge **R**epository, named by myself)[Oh18] is designed as an individual tool, which also works as an assistant that helps thinking about the mathematical subjects. MaKR is a mathematical Web-based system whose contents are glued by an original LaTeX-like formatting language (low-)OFM that are designed under the concept of pushdown automaton, whose translator form OFM to HTML is written in Perl and named *ofm2html*. For the management of resources, a special-purpose Web browser called *MaKRV* is designed. Recently, The use of MathJax
enhanced the mathematical representation.

Formulas in images MathType Some mathematical symbols are broken into graphics, so they are embedded using Illustrator.

Photos (Miyajima , Paris, etc.) are taken by myself, (some of them may have been purchased).
