\label{sec:access_protocols}
We envision two possible access protocols that will be specified in separate documents:
\begin{itemize}
\item ProvSAP (for Simple Access Protocol): retrieve provenance information based on given ID of a data entity or activity.
\item ProvTAP (for Table Access Protocol): allows detailed queries for provenance information, discovery of datasets based on e.g. code version, parameter values of a specified kind of Activity, etc.
\end{itemize}

% \subsection{VOSI availability and capabilities}
% According to the DALI specification for VO services \citep{std:DALI}, a provenance service implementing ProvDAL must provide a VOSI availability interface as well as a capabilities interface with entries for ProvDAL. The \texttt{standardId}s for these provenance interfaces are:

% \begin{verbatim}
% ivo://ivoa.net/std/ProvenanceDM#ProvDAL-1.0
% \end{verbatim}

% The capability for a service to support the ProvenanceDM is expressed by
% the dataModel element as:
% \begin{verbatim}
% <dataModel ivoid="ivo://ivoa.net/std/ProvenanceDM-1.0">
%   ProvenanceDM-1.0
% </dataModel>
% \end{verbatim}
