Developments and innovations to Goobi workflow in August 2020
In the coming weeks we will probably focus on the following points:
- Implementation of a tectonics processing mask
- Extension of metadata processing for a better handling of corporate bodies
- Other general plugin developments
- Preparation of the Goobi days :)
In August we developed a number of new plugins for partly completely new working methods. The first plugin to be mentioned here concerns the mass upload. This plugin has already been around for some time. It allows you to upload several images or read them from a directory to automatically assign them to the correct processes. The previous functionality was limited to recognising the correct Goobi processes on the basis of the file names. With the new development, it is now also possible to recognise a barcode on images so that the image with the barcode and all subsequent images up to the next image with barcode are assigned to the process from the barcode.
Sample images with barcodes on separator sheets
With this plugin, completely new working methods are now possible, where images created across objects are automatically divided into independent entities and assigned to the correct workflows.
The mass upload plugin recognises the barcodes in the uploaded images and assigns the processes to the correct operations.
The detailed documentation of the plugin can be found at the following URL:
https://docs.goobi.io/goobi-workflow-plugins-en/workflow/plugin-workflow-massupload

The source code of the plugin itself is available at the following URL:
GitHub - intranda/goobi-plugin-workflow-massupload: This workflow plugin allows a mass upload of files with automatic allocation to the correct Goobi processes either on the basis of the file names or by means of the analysed barcodes.

A new plugin now enables Goobi workflow to scale images as required in a single step. You can specify the maximum size of the scaled image on its longest side in a configuration file. You can also configure a watermark to be included in the image. This can consist of text as well as graphic elements. It is also possible to control where exactly the watermark should be inserted.
Scaled image with automatically added watermark
The definition of how the scaling and creation of the watermark should be done is controllable within the plugin configuration for different workflows. For example, a configuration for the image shown here would look like this within the file
plugin_intranda_step_image_resize_and_watermark.xml:<config_plugin>
<gmPath>/usr/local/bin/gm</gmPath>
<convertPath>/usr/local/bin/convert</convertPath>
<config>
<!-- which projects to use for (can be more than one, otherwise use *) -->
<project>*</project>
<step>*</step>
<sourceDir>master</sourceDir>
<destDir>media</destDir>
<imageConfig collection="*" mediaType="*">
<resizeTo>1500</resizeTo>
<watermark>
<image>/opt/digiverso/goobi/watermark.png</image>
<location>south</location>
<xDistance>0</xDistance>
<yDistance>150</yDistance>
</watermark>
</imageConfig>
</config>
</config_plugin>

The source code of the plugin itself is available at the following URL:
GitHub - intranda/goobi-plugin-step-image-resize-and-watermark: This step plugin allows to scale images down to a specific size of the longest side and adds a configurable watermark. The input and output folder can be configured as well.

Plug-ins for querying catalogues have been available in Goobi since 2009, although until now it has always been sufficient to query a single record from a catalogue using a specific identifier. However, in one of the most recent projects in which we were involved, it became clear that there was also a need for more complex queries. Specifically, depending on the catalogue selection, one, two or even three identifiers should be used together in the catalogue query to obtain a concrete record. For this reason, the interface for Opac plugins had to be extended in such a way that such plugins can now control an additional area in which further entries should be possible. In the case of the JSON Opac plugin, this has been put into productive operation and the interface is now different from the Opac plugins of the past. In addition to the input of an identifier at least one line with additional information is now possible.
The JSON-Opac-Plugin provides a more complex input area for the combinable identifiers for catalogue queries.
Details of what the JSON Opac plugin does, how it is configured and put into operation can be found in the documentation here:

The plugin's source code can be found on GitHub here:

After we have already put a lot of energy into supporting accessibility according to WCAG 2.1 in the past weeks, we had to work on it further in the METS Editor. The work has not yet been fully completed, so that this will continue to accompany us in September.
Accessiblity in the METS Editor is not yet as good as it should be. The work is still going on here.
In our major conversion of Goobi workflow for operation within the Amazon cloud, we have now included Amazon SQS. From now on, the queue for computationally intensive work as externally executable tasks can also be based on Amazon SQS. This further simplifies integration into an infrastructure maintained in AWS.
