\chapter{Protocol Definitions}
\section{Input Data Validation}
\subsection{Name}
\label{protocoldef:inputvalidation:name}
First transform to lowercase and remove whitespaces everywhere in the String. Then check against\\
\verb|^[a-z0-9._\-]{3,40}$|
\subsection{Bcrypt Hash}
\label{protocoldef:inputvalidation:bcrypt}
\verb|^\$2[aby]?\$\d{1,2}\$[.\/A-Za-z0-9]{53}$|
\subsection{Email Address}
\label{protocoldef:inputvalidation:email}
\verb|/.+@.+\..+/i|\\
The user MMI should do a precheck on the email address. Example for NodeJs: \url{https://github.com/mailcheck/mailcheck}.
\subsection{Roles}
\label{protocoldef:inputvalidation:roles}
Get the actual set of allowed roles from the Auth Service at startup and check that the given value is in the returned array. See \ref{protocoldef:auth:api} for the API call to the Auth Service.
The JSON Value must be an Array with at least one entry. All entries must be a valid role. All entries have to be different, no repetitions of given roles are allow. They have to be filtered out if they exist.
\subsection{Auth Key}
\label{protocoldef:inputvalidation:authkey}
\verb|^[a-zA-Z0-9]{3,40}$|
\subsection{Owners}
\label{protocoldef:inputvalidation:owners}
Each entry of the array must validate successfully against \ref{protocoldef:inputvalidation:name}. No checking, if username is existing. The array must contain at least one element.
\subsection{Rubric Number}
\label{protocoldef:inputvalidation:rubricnumber}
The rubric number must be an integer >= 1 and <= 95.
\subsection{Rubric Label}
\label{protocoldef:inputvalidation:rubriclabel}
String with only \verb|a-zA-Z0-9_-| and max length of TBD.
\subsection{Transmitter Groups}
\label{protocoldef:inputvalidation:transmittergroup}
String with only \verb|a-zA-Z0-9_-| and max length of TBD.
\subsection{Rubric Cyclic Transmit Interval}
\label{protocoldef:inputvalidation:cyclictransmitinterval}
Integer value between 0 and 60*60*24*30.
\subsection{Description}
\label{protocoldef:inputvalidation:description}
The description has to be a string with arbitrary content. Max length 45 characters.
\subsection{RIC}
\label{protocoldef:inputvalidation:ric}
Integer value between 1 and $2^{21}-1$. There are reserved ranges that are not usable (i.e. 0-7, 2007664-2007671, 2045056-2045063).
\subsection{Function Bits}
\label{protocoldef:inputvalidation:function}
Integer value >= 0 and <= 3.
\subsection{Pager Type}
\label{protocoldef:inputvalidation:pagertype}
String
\todo{TBD}
\subsection{Transmitter Usage}
\label{protocoldef:inputvalidation:usage}
Valid values are \verb|wirerange| or \verb|personal|.
\subsection{Transmitter Timeslots}
\label{protocoldef:inputvalidation:timeslots}
A JSON Array of \textbf{exact} 16 boolean values.
\subsection{Transmitter Output Power}
\label{protocoldef:inputvalidation:power}
Float Value, > 0, round to 2 decimals. Max value 1000
\subsection{Coordinates}
\label{protocoldef:inputvalidation:coordinates}
JSON Array of two float, may be negative.
\todo{check ranges}
\subsection{Transmitter Antenna Type}
\label{protocoldef:inputvalidation:antennatype}
String
\todo{define}
\subsection{Transmitter Antenna Gain}
\label{protocoldef:inputvalidation:antennagain}
Float, can be negative min = -40, max = 40
\subsection{Transmitter Antenna Direction}
\label{protocoldef:inputvalidation:antennadirection}
Integer, if given as float -> round. Then modulo 360
\subsection{Transmitter Antenna Height}
\label{protocoldef:inputvalidation:antennaagl}
Integer, if given as float -> round. Always greater then 0.
\section{Microservices API}
\label{protocoldef:microservicesapi}
\subsection{Preamble}
All HTTP(s) communication should be compress with gzip to reduce network load. That's especially important for the answers to GET-calls of all entity's details.
See \hyperref[internalprog:microservices]{Microservices definition}.
\subsection{Filtering and pagination in detailed lists}
\label{protocoldef:filteringandpagination}
For the endpoints \verb|GET /users|, \verb|GET /nodes|, \verb|GET /transmitters| and \verb|GET /rubrics|, there are the following GET parameters available for pagination and filtering.
\begin{table}[htbp]
\label{tab:protocoldef:permissionmatrix:usersdb}
\begin{tabular}{|l|p{8.5cm}|} \hline
Parameter & Description \\ \hline \hline
\verb|?skip=<n>&limit=<m>| & Used for pagination, just output <m> entries and skip the first <n> ones. \\
& Mapping to CouchDB: transparent \\ \hline
\verb|?startkey="dh3wr"\&endkey="dl2ic"| & Get all entries with an \verb|_id| between \verb|dh3wr| and \verb|dl2ic|. \\
& Mapping to CouchDB: transparent \\ \hline
\verb|?startswith="dh3"| & Get all entries where the \verb|_id| starts with \verb|dh3|. Used for AJAX based search in tables on website. \\
& Mapping to CouchDB: \verb|?startkey="dh3"&endkey="dh3\ufff0"| \\ \hline
\end{tabular}
\caption{Pagination and filtering syntax}
\end{table}
\textbf{Attention:} The parameter \verb|?include_docs=true| has to be included by the Microservice where it is stated in the detailed description below.\\

\subsection{Database Service}
\subsubsection{GET /users}
\label{protocoldef:microservicesapi:database:getusers}
\begin{table}[htbp]
\begin{tabular}{|l|p{12cm}|} \hline
Item & Description \\ \hline \hline
Description & Returns all users (depending on the filtering in \ref{protocoldef:filteringandpagination} in JSON format. \\ \hline
Permission & \verb|user.read| \\ \hline
Mapping to CouchDB & \verb|GET /users/_design/users/_view/byId?include_docs=true|\\ \hline
\end{tabular}
\end{table}
\colorbox{red}{Special treatment for user database: The \texttt{password} field has always to be filtered out.}\\
\textbf{Auth response: \texttt{true}:}
\begin{lstlisting}
