+Top level of json must be a dict. keys of the dict are RT names.
+
+
+Frage: is the first RT never an array?
+
+
+Do not use sheet name, but only content of hidden rows
+
+
+
+Das Datenmodell in LinkAhead legt fest, welche Arten von Records es in einer LinkAhead-Instanz
+gibt und wie diese aussehen. Diese Datenmodell kann auch in einem JSON Schema repräsentiert werden,
+dass die Struktur von JSON Dateien festlegt, die zu dem Datenmodell gehörige Records enthält.
+Zum Beispiel kann das folgende JSON den Record einer Person beschreiben:
+```JSON
+{
+ "Person": {
+ "family_name": "Steve",
+ "given_name": "Stevie"
+ }
+}
+```
+
+Das JSON Schema schreibt eine konkrete Struktur vor und kann zugehörige JSON Dateien können genutzt werden
+um Daten zu bestimmten Record Strukturen zu repräsentieren. Beispielsweise könnte man ein JSON Schema erstellen,
+dass es erlaubt "Training" Records mit Informationen zu abgehaltenen Trainings speichern. Dies ist insbesondere wertvoll
+beim Datenim- und export. Man könnte basierend auf dem im Folgenden beschriebenen Webformulare basieren
+oder es nutzen um in LinkAhead gespeicherte Objekte als JSON zu exportieren.
+
+Im Folgenden wird beschrieben, wie JSON Dateien mit solchen Records in XLSX Dateien umgewandelt
+werden, bzw. wie aus XLSX-Dateien JSON Dateien mit Records erstellt werden.
+
+Der Attributname (oben "Person") legt den RecordType fest und der Wert diese Attributs kann
+entweder ein Objekt oder eine Liste sein. Ist es ein Objekt (wie im obigen Beispiel), so wird ein
+einzelner Record repräsentiert. Bei einer Liste mehrere Records, die den gleichen RecordType als
+Parent haben.
+Die Properties des Records (oben "family_name" und "given_name") werden zu Spalten im XLSX.
+Die Properties haben wiederum einen Attributnamen und einen Wert. Der Wert kann
+a. primitiv (Text, Zahl, Boolean, ...)
+b. ein Record
+c. eine Liste von primitiven Typen
+d. eine Liste von Records
+sein.
+
+In den Fällen a. und c. wird in XLSX eine Zelle in der zur Property gehörigen Spalte erstellt. Im Fall b.
+wird prinzipiell für die Properties des Records Spalten erstellt. Tatsächlich wird der referenzierte Record genauso behandelt wie
+der ursprüngliche. D.h. die Fälle a.-d. werden wieder für die einzelnen Properties betrachtet.
+Für den Fall d. ist die zweidimensionale Struktur eines XLSX Blatts nicht ausreichend. Daher werden für solche Fälle neue XLSX Blätter erstellt.
+In diesen werden die referenzierten Records behandelt wie oben beschrieben. Es gibt jedoch zusätzliche Spalten die es erlauben zu erkennen von
+welchem Record die Records referenziert werden.
+
+Wir betrachten diese vier Fälle nun im Detail:
+a. Properties mit primitiven Datentypen
+
+```JSON
+{
+ "Training": {
+ "date": "2023-01-01",
+ "url": "www.indiscale.com",
+ "duration": 1.0,
+ "participants": 1,
+ "remote": false
+ }
+}
+```
+Dies würde in einem XLSX Blatt mit dem folgenden Inhalt abgebildet:
+
+| date | url | duration | participants | remote |
+|------|-----|-------------------|-----|---|----|
+| 2023-01-01 | www.indiscale.com | 1.0 | 1 | false |
+
+b. Property, die einen Record referenziert
+
+
+```JSON
+{
+ "Training": {
+ "date": "2023-01-01",
+ "supervisor": {
+ "family_name": "Steve",
+ "given_name": "Stevie",
+ }
+ }
+}
+```
+
+Dies würde in einem XLSX Blatt mit dem folgenden Inhalt abgebildet:
+
+| date | supervisor.family_name | supervisor.given_name |
+|------|-----|-------------------|
+| 2023-01-01 | Steve | Stevie |
+
+Beachten Sie, dass die Spaltennamen umbenannt werden dürfen. Die Zuordnung der Spalte zu Properties von
+Records wird über den Inhalt von versteckten Zeilen gewährleistet.
+
+c. Properties, die Listen mit Werten von primitiven Datentypen enthalten
+
+
+```JSON
+{
+ "Training": {
+ "url": "www.indiscale.com",
+ "subjects": ["Math", "Physics"],
+ }
+}
+```
+
+Dies würde in einem XLSX Blatt mit dem folgenden Inhalt abgebildet:
+
+| url | subjects |
+|------|-----|-------------------|-----|---|----|
+| www.indiscale.com | Math;Physics |
+
+
+Die Listenelemente werden separiert von ``;`` in die Zelle geschrieben.
+Wenn die Elemente den Separator ``;`` enthalten, dann wird dieser mit einem ``\`` escaped.
+
+
+d. Properities, die Listen mit Referenzen enthalten
+
+
+```JSON
+{
+ "Training": {
+ "date": "2023-01-01",
+ "coach": [
+ {
+ "family_name": "Sky",
+ "given_name": "Max",
+ },{
+ "family_name": "Sky",
+ "given_name": "Min",
+ }],
+ }
+}
+```
+
+Da die beiden Coaches nicht vernünftig in einer Zelle dargestellt werden können, bedarf es nun eines
+weiteren Tabellenblatts, das die Eigenschaften der Coaches enthält.
+
+Das Blatt zu den Trainings enthält in diesem Beispiel nur die "date" Spalte:
+
+| date |
+|------|
+| 2023-01-01 |
+
+Zusätzlich gibt es ein weiteres Blatt in dem die Coaches gespeichert werden.
+Hier ist nun entscheidend, dass definiert wird, wie von potentiell mehreren "Trainings" das richtige Element gewählt wird.
+In diesem Fall bedeutet dies, dass das "date" eindeutig sein muss
+TODO: In welchem Scope gilt diese Eindeutigkeit? Können wir dies checken?
+Das zweite Blatt sieht dann wie folgt aus
+
+| date | coach.family_name | coach.given_name |
+|------|-|-|
+| 2023-01-01 | Sky | Max|
+| 2023-01-01 | Sky | Min|
+
+
+
+# Hidden automation logic
+
+The first column in each sheet will be hidden and it will contain an entry in each row that needs special
+treatment. The following values are used:
+``COL_TYPE``: typically the first row. It indicates the row that defines the type of columns (``FOREIGN`` or ``VALUE``).
+``PATH``: indicates that the row is used to define the path within the JSON
+``IGNROE``: row is ignored; It can be used for explanatory texts or layout
+
+If we want to put the value of a given cell into the JSON, we traverse all path elements given in rows with the ``PATH`` value from row with lowest index to the one with the highest index. The final element of the path is the name of the Property of which the value
+needs to be set. The elements of the path are sufficient to identify the object within the JSON if the value of the corresponding key is
+an object. If the value is an array, the appropriate object within the array needs to be selected.
+For this selection additional ``FOREIGN`` columns are used. The path given in those columns is the path to the level where the object needs to be chosen plus the name of the attribute that is used to select the correct object.

+<p>Top level of json must be a dict. keys of the dict are RT names.</p>
+<p>Frage: is the first RT never an array?</p>
+<p>Do not use sheet name, but only content of hidden rows</p>
+<p>Das Datenmodell in LinkAhead legt fest, welche Arten von Records es
+in einer LinkAhead-Instanz gibt und wie diese aussehen. Diese
+Datenmodell kann auch in einem JSON Schema repräsentiert werden, dass
+die Struktur von JSON Dateien festlegt, die zu dem Datenmodell gehörige
+Records enthält. Zum Beispiel kann das folgende JSON den Record einer
+Person beschreiben:</p>
+<div class="sourceCode" id="cb1"><pre
+class="sourceCode json"><code class="sourceCode json"><span id="cb1-1"><a href="#cb1-1" aria-hidden="true" tabindex="-1"></a><span class="fu">{</span></span>
+<span id="cb1-2"><a href="#cb1-2" aria-hidden="true" tabindex="-1"></a> <span class="dt">"Person"</span><span class="fu">:</span> <span class="fu">{</span></span>
+<span id="cb1-3"><a href="#cb1-3" aria-hidden="true" tabindex="-1"></a> <span class="dt">"family_name"</span><span class="fu">:</span> <span class="st">"Steve"</span><span class="fu">,</span></span>
+<span id="cb1-4"><a href="#cb1-4" aria-hidden="true" tabindex="-1"></a> <span class="dt">"given_name"</span><span class="fu">:</span> <span class="st">"Stevie"</span></span>
+<span id="cb1-5"><a href="#cb1-5" aria-hidden="true" tabindex="-1"></a> <span class="fu">}</span></span>
+<span id="cb1-6"><a href="#cb1-6" aria-hidden="true" tabindex="-1"></a><span class="fu">}</span></span></code></pre></div>
+<p>Das JSON Schema schreibt eine konkrete Struktur vor und kann
+zugehörige JSON Dateien können genutzt werden um Daten zu bestimmten
+Record Strukturen zu repräsentieren. Beispielsweise könnte man ein JSON
+Schema erstellen, dass es erlaubt “Training†Records mit Informationen
+zu abgehaltenen Trainings speichern. Dies ist insbesondere wertvoll beim
+Datenim- und export. Man könnte basierend auf dem im Folgenden
+beschriebenen Webformulare basieren oder es nutzen um in LinkAhead
+gespeicherte Objekte als JSON zu exportieren.</p>
+<p>Im Folgenden wird beschrieben, wie JSON Dateien mit solchen Records
+in XLSX Dateien umgewandelt werden, bzw. wie aus XLSX-Dateien JSON
+Dateien mit Records erstellt werden.</p>
+<p>Der Attributname (oben “Personâ€) legt den RecordType fest und der
+Wert diese Attributs kann entweder ein Objekt oder eine Liste sein. Ist
+es ein Objekt (wie im obigen Beispiel), so wird ein einzelner Record
+repräsentiert. Bei einer Liste mehrere Records, die den gleichen
+RecordType als Parent haben. Die Properties des Records (oben
+“family_name†und “given_nameâ€) werden zu Spalten im XLSX. Die
+Properties haben wiederum einen Attributnamen und einen Wert. Der Wert
+kann a. primitiv (Text, Zahl, Boolean, …) b. ein Record c. eine Liste
+von primitiven Typen d. eine Liste von Records sein.</p>
+<p>In den Fällen a. und c. wird in XLSX eine Zelle in der zur Property
+gehörigen Spalte erstellt. Im Fall b. wird prinzipiell für die
+Properties des Records Spalten erstellt. Tatsächlich wird der
+referenzierte Record genauso behandelt wie der ursprüngliche. D.h. die
+Fälle a.-d. werden wieder für die einzelnen Properties betrachtet. Für
+den Fall d. ist die zweidimensionale Struktur eines XLSX Blatts nicht
+ausreichend. Daher werden für solche Fälle neue XLSX Blätter erstellt.
+In diesen werden die referenzierten Records behandelt wie oben
+beschrieben. Es gibt jedoch zusätzliche Spalten die es erlauben zu
+erkennen von welchem Record die Records referenziert werden.</p>
+<p>Wir betrachten diese vier Fälle nun im Detail: a. Properties mit
+primitiven Datentypen</p>

+<p>Zusätzlich gibt es ein weiteres Blatt in dem die Coaches gespeichert
+werden. Hier ist nun entscheidend, dass definiert wird, wie von
+potentiell mehreren “Trainings†das richtige Element gewählt wird. In
+diesem Fall bedeutet dies, dass das “date†eindeutig sein muss TODO: In
+welchem Scope gilt diese Eindeutigkeit? Können wir dies checken? Das
+zweite Blatt sieht dann wie folgt aus</p>
+<table>
