Hi Gregg,

Online source appears to be viewable at:

The stable (4.4) version of the IMetadata class you're looking for is best found on github: https://github.com/openmicroscopy/bioformats/blob/dev_4_4/components/scifio/src/loci/formats/meta/IMetadata.java, and the overall documentation under https://www.openmicroscopy.org/site/support/bio-formats4/

The upcoming major release (5.0) has moved this class and it is now available on github at https://github.com/openmicroscopy/bioformats/blob/dev_5_0/components/ome-xml/src/ome/xml/meta/IMetadata.java. For full documentation, see https://www.openmicroscopy.org/site/support/bio-formats5/

Cheers,
~Josh

Hi Gonzalo and Gregg,

In addition to what Josh has linked, please note that the IMetadata interface is closely tied to the OME-XML schema, so you may find it useful to reference the schema when reading the interface Javadoc. The schema version used by Bio-Formats 4.4.x is here:

http://www.openmicroscopy.org/Schemas/O ... 06/ome.xsd

and the version used by Bio-Formats 5.0.x is here:

http://www.openmicroscopy.org/Schemas/O ... 06/ome.xsd

If you have questions about what specific IMetadata methods or schema values are used for, or are unsure of which methods to call to set a specific piece of metadata, then please let us know.

Regards,
-Melissa

Hi Melissa.

We continue seeing information about how to use the IMetadata interface. We want to ask you some questions about the following example:
https://github.com/openmicroscopy/biofo ... eTiff.java

We don't understand lines 55 to 57.
ServiceFactory factory = new ServiceFactory();
OMEXMLService service = factory.getInstance(OMEXMLService.class);
IMetadata omexmlMeta = service.createOMEXMLMetadata();

What is the concept behind "service"? Why do you use it?
Where do you link the Java objects with the XML model? In some of this methods?


On the other hand, do you have an example where you add an SA:AnnotationRef to an Image element (not in the OME element) in a xml file?


Regards,
Gonzalo

I am sure that Melissa will soon get to helping you with the OME-XML aspects but in the meantime I can mention that it is through services offered by the OMERO server that the clients can communicate with it and make requests of it, generally within the context of an authenticated session. Various services are offered by the server, including the meta-data service, each with their own methods appropriate for their purpose. One may read more about the services at http://www.openmicroscopy.org/site/supp ... s/Api.html and about the object model mapping at http://www.openmicroscopy.org/site/supp ... Model.html. I hope that there may be something among that documentation that provides further illumination for your endeavors.

Cheers,
Mark

Similar to the remote services for OMERO that Mark mentions, in Bio-Formats services allow us to abstract away certain implementation details. For example, if certain libraries are not installed, your code can still be compiled because use of the library is behind an interface.

Here's an example OME-XML file with Structured Annotations. https://gist.github.com/will-moore/9507510

Hope it has the info you need.

Will.

Thanks Mark and Josh.
Despite of we have read the links, we continue confused about where the XML model is mapped with the Java objects. Where do you say to the program that you are going to use this schema: http://www.openmicroscopy.org/Schemas/O ... 06/ome.xsd?

Thanks Will.
We already had that example. We are looking another one where the Image element has an SA:AnnotationRef. This is the xsd:element that appears before the xsd:attributes ID and Name. (we are trying to use the schema http://www.openmicroscopy.org/Schemas/O ... 06/ome.xsd). If you have one example using this element, we would appreciate you send it to us.

Gonzalo

Hello Gonzalo,

If you are building using maven the current schema is set in 'pom.xml' using '<xsdfu.schemaver>'.
If you are building using ant the current schema is set in 'ant/xsd-fu.xml' using 'property name="xsdfu.schemaver"'.

A minimal xml block for an Image with an Annotation using the 2013-06 schema is:

Code: Select all

Thanks Andrew,

We keep doing tests in the OMERO server.
We had a problem with the metadata block: we couldn't view the description nor the experimenter of the image. Are these metadatas displayed in the OMERO.insight?

I attached the xml file that we extracted with the tiffcomment command. It was validated with the xmlvalid command.

Code: Select all

<?xml version="1.0" encoding="UTF-8"?><!-- Warning: this comment is an OME-XML metadata block, which contains crucial dimensional parameters and other important metadata. Please edit cautiously (if at all), and back up the original data before doing so. For more information, see the OME-TIFF web site: http://ome-xml.org/wiki/OmeTiff. -->
