Hello,<br class="">
<br class="">
In our microscope software, we have an exporter to OME-TIFF. Following the OME schema of 2013, we save the image transformation needed of some (fluorescence) images to align them on some other (SEM) images using the Image/Transform attribute:<br class="">
<a href="http://www.openmicroscopy.org/Schemas/Documentation/Generated/OME-2013-06/ome_xsd.html#Image_Transform" class="">http://www.openmicroscopy.org/Schemas/Documentation/Generated/OME-2013-06/ome_xsd.html#Image_Transform</a><br class="">

Hi Éric,<br class="">
<br class="">
Adding a Transform attribute to the Image had been considered for inclusion in the 2013-06<br class="">
schema but this addition has been reverted late in the development process - see [1] [2].<br class="">
<br class="">
As you rightfully reported, the live oXygen documentation had not been updated from a
<div class="">development version of this schema and was erroneous documenting this element. We have</div>
<div class="">now regenerated our set of schema documentations to prevent confusion.<br class="">
<br class="">
<blockquote type="cite" class="">While trying to update our code to use the newer schema, I've realised that this attribute is gone in 2015-01 (and 2016-06). There is no mention of this in the changelog, nor in the XSLT transformations.<br class="">
</blockquote>
<br class="">
The Image.Transform attribute was not included as part of the 2013-06 Data Model which is </div>
<div class="">why neither the Model documentation nor the Transforms mention it. Having published a</div>
<div class=""> outdated schema documentation is entirely our mistake and we accept full responsibility for it.</div>
<div class="">As a consequence the OME-TIFF files generated by your software using this attribute might</div>
<div class="">be invalid as you can verify using the xmlvalid tool [3].<br class="">
<br class="">
<blockquote type="cite" class="">There is still 'Shape/Transform', but it's not clear to me how it can be used as replacement.<br class="">
</blockquote>
<br class="">
At the moment, Transforms are only used in the context of Regions of Interest although we have</div>
<div class="">certainly heard interest in modelling it for images as well.<br class="">
<br class="">
<blockquote type="cite" class="">Could anyone confirm this attribute was intentionally removed? Is there a suggested way to convey the same information with newer OME schema versions?<br class="">
<br class="">
</blockquote>
Our best recommendation would be to annotate the Image with a MapAnnotation using a custom</div>
<div class="">namespace and store the Transform elements as key/value pairs - see [4] for an example. These</div>
<div class="">annotations are completely supported across our software stack and will be maintained over model</div>
<div class="">upgrades.<br class="">
<br class="">
We sincerely apologize for this serious documentation issue. Thanks for raising it and please let us</div>
<div class="">know if we can assist further in the upgrade of your exporter functionality.<br class="">
<br class="">
</div>
<div class="">Best regards,<br class="">
