<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hi Nico,<br>
<br>
Not sure what are you trying to do here.<br>
Do you need to improve the h5m reader writer? Or do you try to understand how are the data / tags stored?<br>
<br>
Do you have a specific problem/bug ? <br>
Suggestions for improvement? <br>
<br>
All these attributes are part of specific moab conventions and hdf5 format. Not much documentation, except what you already found.<br>
<br>
class would correspond to the type of the tag (integer, double, opaque, etc)<br>
default would be the default value<br>
<br>
global is used if the tag is "global", in the sense it refers to the whole mesh instance<br>
<br>
"The tag sub-group may have any or all of the following four attributes: <tt>default</tt>,
<tt>global</tt>, <tt>is_handle</tt>, and <tt>variable_length</tt>. The <tt>default</tt> attribute, if present, must contain a single tag value that is to be considered the 'default' value of the tag. The
<tt>global</tt> attribute, if present, must contain a single tag value that is the value of the tag as set on the mesh instance (MOAB terminology) or root set (ITAPS terminology.) The presence of the
<tt>is_handle</tt> attribute (the value, if any, is meaningless) indicates that the tag values are to be considered entity IDs."<br>

<div dir="ltr">Hi everyone,
<div><br>
</div>
<div>In h5m files [1], I see that tstt->tags typically have three attributes:</div>
<div><br>
</div>
<div> * class</div>
<div> * default</div>
<div> * global</div>
<div><br>
</div>
<div>Where can I find documentation on these attributes?</div>
<div><br>
</div>
<div>Cheers,</div>
<div>Nico</div>
