====== Data Resource - Data URI ======


===== About =====
A ''Data URI'' or ''Data Uniform Resource Identifier'' is [[attribute|data resource attribute]] that identify uniquely a [[docs:resource:resource|data resource]].

<note>
It's a syntax that extends the notion of [[wp>Uniform%20resource%20identifier|URI]]
</note>


<note tip>
If you use it as [[..:flow:data_selector|data selector]], you would select only [[docs:resource:resource|one data resource]].
</note>



===== Syntax =====
==== Content / Container ====

For a [[content|content data resource]] or [[container|container data resource]]
<code bash>
path@connection
</code>
where:
  * ''path'' is the [[path|path]]
  * ''connection'' is the [[docs:connection:name|connection name]]

==== Runtime ====

For a [[runtime|runtime data resource]], we use a special ''data uri'' syntax:
<code bash>
(executablePath@executableConnection)@executionConnection
</code>
where:
  * ''executablePath@executableConnection'' is the ''data uri'' of the executable [[:docs:resource:file|file]]
  * ''executionConnection'' is the [[docs:connection:name|connection name]] where the executable is executed

===== Management =====
==== See ====
As a ''data uri'' is a [[attribute|data resource attribute]], you can see it with


  * the [[docs:tabul:data:list|data list command]]
<unit>
<code bash>
tabul data list -a data-uri characters.csv@howto
</code>
<console>
path             media_type   data_uri
--------------   ----------   --------------------
characters.csv   text/csv     characters.csv@howto
</console>
</unit>
  * or more verbose the [[docs:tabul:data:info|data info command]]
<unit>
<code bash>
tabul data info characters.csv@howto
</code>
<console>
