P-Lingua is a programming language for membrane computing which aims
to be a standard to dene P systems. In order to implement this idea, a Java library
called pLinguaCore has been developed as a software framework for cell-like P systems.
It is able to handle input les (either in XML or in P-Lingua format) dening P systems
from a number of dierent cell{like P system models. Moreover, the library includes
several built-in simulators for each supported model. For the sake of software portability,
pLinguaCore can export a P system denition to any convenient output format (currently
XML and binary formats are available). This software is not a closed product, but it can
be extended to accept new input or output formats and also new models or simulators.
The term P-Lingua 2.0 refers to the software package consisting of the above mentioned
library together with a user interface called pLinguaPlugin (more details can be
found at http://www.p-lingua.org).
Finally, in order to illustrate the software, this paper includes an application using
pLinguaCore for describing and simulating ecosystems by means of P systems.
