For example, most of the authors of *this* paper were not<br>
involved in “our reproducibility study”. It is also unclear if<br>
“we decided to continue with CC0” refers to BioModels or the<br>
present paper.<br>
<br>
I would prefer an explanation from first principles with<br>
BioModels as a good example. Something like the text below.<br>
<br>
(Aside #1. I removed the word “sophisticated” from Sheriff’s<br>
text. Feel free to put it back. I’ve observed the pattern,<br>
particularly around the pandemic, of pointing to complicated<br>
models as better evidence of something than can be got with<br>
simpler models. As though being complicated is a virtue. This<br>
is more akin to the original meaning of the word sophisticated<br>
which is a scientific anti-pattern. That’s not what Sheriff<br>
meant, but I’d like to avoid using that word at all, especially<br>
in a context that suggests it’s something good.)<br>
<br>
(Aside #2. For software, I personally prefer copyleft licenses<br>
and not usually public domain. In the academic sphere this<br>
*should* not pose a problem because of the norm that says you<br>
have to make your code available otherwise the paper that <br>
crucially relies on it isn’t worth the bits it’s encoded in.<br>
However it’s not at all obvious that it’s enough to rely on<br>
good practice for this since there’s plenty of bad practice<br>
out there. There is some progress with journals and funders<br>
enforcing better practice. This is just an alternative mechanism<br>
to the legal jiu-jitsu of copyleft.)<br>

There are practical and moral reasons why models should be<br>
freely available. To ensure a high standard of scientific<br>
work, it is important to be able to reproduce and verify<br>
results. This requires software and data for models to be<br>
freely available and that the barriers to running them <br>
be minimal. To facilitate scientific progress, it is<br>
ideal to be able to build upon the work of others. This<br>
requires not only that software and data are available but<br>
that reuse and modification is allowed. Finally, there is<br>
a moral argument that work produced using public funds <br>
should be publicly available. This concept is well embedded<br>
in some segments of the community, for example in the case<br>
of federally funded work in the United States, but we hold<br>
it as a general principle.<br>
<br>
Models are a combination of software and data. The legal <br>
treatment of these differs across jurisdictions with software<br>
generally subject to copyright law and data subject to database<br>
rights. This is not universal. The common denominator is the<br>
maximally permissive concept of “public domain” which exists<br>
in some jurisdictions where no restrictions are placed on use,<br>
reuse, modification and creation of derivative works, and, <br>
crucially, combination of multiple (possibly derivative) works<br>
into a new whole. However, the public domain does not exist<br>
as a concept in all jurisdictions and in others it is not<br>
possible to simply place a work in it. To solve this problem,<br>
the CC0 license (formulated with respect to copyright law<br>
and database rights) emulates the public domain in jurisdictions<br>
where this is necessary. We therefore recommend that models,<br>
and their associated data are published under CC0 terms.<br>
<br>
An example of this approach is the BioModels database. BioModels provides model curation and annotation service, where the models’<br>
reproducibility is assessed and annotated with controlled<br>
vocabularies. BioModels aims to make models discoverable. The <br>
BioModels database offers search engines to search and locate<br>
models and model components (<a href="https://www.ebi.ac.uk/biomodels/parameterSearch" rel="noreferrer noreferrer noreferrer noreferrer noreferrer" target="_blank">https://www.ebi.ac.uk/biomodels/parameterSearch</a>). The BioModels<br>
reproducibility study ( Tiwari et al. 2021,<br>
<a href="https://doi.org/10.15252/msb.20209982" rel="noreferrer noreferrer noreferrer noreferrer noreferrer" target="_blank">https://doi.org/10.15252/msb.20209982</a>), strongly recommends<br>
that authors make their models public, but more specifically <br>
through public repositories such as BioModels (<a href="https://www.ebi.ac.uk/biomodels" rel="noreferrer noreferrer noreferrer noreferrer noreferrer" target="_blank">https://www.ebi.ac.uk/biomodels</a>).<br>
We also recommend that authors submit model codes, parameter sets,<br>
and simulation conditions needed to reproduce simulation<br>
studies. Overall this will greatly facilitate model reuse.<br>
<br>
We further recommend that models published in this way should<br>
not require proprietary software or resources in order to be<br>
used. Requiring such resources greatly hampers reproducibility, verification and reuse. To achieve these goals, such <br>
dependencies typically require rewriting the models ab initio<br>
with the original model code serving the much less useful <br>
(but still not worthless) function of documentation. While<br>
there are benefits to reformulating existing models — a <br>
reimplementation might be more efficient or clearer and more<br>
elegant — a hard requirement to do so in all cases simply<br>
leads to wasted resources.<br>
