\section{Data management plan} 

The ASU Meson Physics Group, as a member of the CLAS Collaboration and the GlueX Collaboration,
adheres to the data management practices of those groups, which are
consistent with best practices in the field. 
As is common in experimental hadronic physics, 
the data obtained from experiments
pass through three stages:
raw data, calibrated (or ``cooked'') data, and final results. 
Data in the first two stages are kept in the storage facilities at Jefferson Lab,
where those data can be accessed and utilized by institutions, like ASU,
that are in the particular collaboration  
within which the data were taken. 
As analyses proceed to the results stage,
preliminary results are disseminated in talks and presentations. 
With final collaboration approval, the results are published in 
refereed journals and placed in collaboration archives for public access.

\vskip0.125in{\bf{Expected data:}}  Raw and cooked data are stored physically
at JLab. Those JLab storage resources
are multiply redundant in order to prevent any data loss. 
As is the case for other groups,
the ASU Meson Physics Group makes copies of portions (or, in some cases, the entirety)
of the cooked data for a given running period 
temporarily using hard drives on computer resources local to the 
group; that temporary storage also is usually on redundant devices. 
Thus, at any point in the raw and cooked stages, a given set of data may exist
on many other sites than JLab, so preservation is robust.
There generally is no attempt by a local group to permanently store
cooked data on local resources. 
In case of local hardware failures or human error leading to the loss
of data on local resources, those data are re-copied onto 
local hardware from the original copies at JLab.  
Once final results are published, those results
%, the cooked data files are erased from our storage resources 
%and the final results 
are placed on
archives accessible to the general public (e.g. Refs. \cite{clasDatabase,SAIDdatabase}).

\vskip0.125in{\bf{Data format:}} 
%The CLAS Collaboration chose the BOS format for raw and cooked data.
%The BOS format is used by other groups in the nuclear/particle 
%physics communities. A CLAS-Note for the CLAS event format within 
%the BOS framework can be found in reference \cite{bosnote}. 
The data
format for raw and cooked data for the GlueX and CLAS collaborations,
called EVIO, 
was developed by JLab;
documentation describing the EVIO format is available in Ref.  
\cite{evioUserGuide}. 

\vskip0.125in{\bf{Access and data sharing:}} Raw and cooked data are accessible to members of each collaboration.
A person or institution desiring access to the raw and cooked data must apply
and be accepted
for membership within the CLAS or GlueX collaborations.
The final data products of the ASU Meson Physics Group, 
consisting primarily of cross sections and spin observables, are made
publicly available through publications, talks, and presentations,
as well as in databases such 
as the SAID database \cite{SAIDdatabase} and CLAS Archive \cite{clasDatabase}.

\vskip0.125in{\bf{Policies for re-use and re-distribution:}} Preliminary results 
often are presented at open national and international scientific conferences.
These preliminary results are internally reviewed within the respective collaboration prior to presentation,
with permission obtained to present the preliminary results required
by the collaboration prior to the presentation. 
Such preliminary results are useful in the the initial development of physical interpretations,
and comparison with other world data. Reproduction of preliminary results
is not  permitted without explicit permission of the respective collaborations. 
Once results have been through the full 
internal review process within each collaboration, the results are deemed ``final''.
The data products are submitted to professional journals and 
made available in public databases such as the SAID database 
\cite{SAIDdatabase} and the CLAS Archive \cite{clasDatabase}.


\vskip0.125in{\bf{Archiving of data:}}
As noted above, the raw and cooked data for data runs are archived on tape on-site at 
JLab. Final results are archived in databases such as the SAID 
database \cite{SAIDdatabase} and the CLAS Archive \cite{clasDatabase}.
