Particle physics research seeks to understand the fundamental constituents of matter and their interactions. As part of the standard model of particle physics, Quantum Chromodynamics (QCD) is the quantum field theory underlying the strong interactions. This theory explains the formation of hadrons, i.e., composite particles such as the proton and neutron found in atomic nuclei. Lattice QCD is a numerical formulation of QCD, and its development over decades has provided crucial insights into the internal structure of hadrons. The workflows of Lattice QCD involve computationally immense tasks including the generation and manipulation of large amounts of data. A proper description of these workflows and the tracking of the associated metadata is essential and allows for the validation of results at any stage.

We have previously established a provenance model for the two generic parts of the Lattice QCD workflow (generation and measurement). The model is based on the W3C PROV standard. In this paper, we again follow this standard and extend our model by the third part of the workflow (the analysis part). For the generation part of the workflow a community metadata standard (QCDml) exists, which includes provenance information. There are no uniform standards for the other two parts. As a first step towards such standards, we introduce the concept of a ProvCard to isolate the provenance-related metadata. ProvCards allow us to answer typical provenance questions quickly and independently of other (meta-) data. Furthermore, we can automatically generate provenance graphs from ProvCards. We present an outline of the toolbox provQCD, which will implement the corresponding functionalities.
