Links to external URLs in results table

You can add links to any column in the results table. In some cases, you can even include columns only to contain links.

In our example we include three different links:

• A link in the ID column pointing that will go to the entry for the same filter in the SVO Filter Profile Service.
• A link in the so called "lnk_dat" column to download the transmission data for the filter.
• A link in the so called "lnk_png" column to show, only in VO services, the url to download the transmission plot. This link does not apply to the catalogue web presentation.

See that you can use, in some configuration options, {$MYFIELD} as a place holder that will be replace with the value of the MYFIELD column for each catalogue entry.

Links with OpenWindow in results table

You can also include links that open a windows displaying some content. This is often used to preview some images associated to catalogue entries. But other types of html content could be displayed.

In the case of our example catalogue we include a link that will open a window showing a preview of the filter transmission curve.

This only applies to the web presentation of the catalogue. That's why in the section above we have included a link to download the plot only in the VO services and we include here the preview of the curve in the web service.

Datalink configuration

Datalink is a VO protocol designed to associate links to catalogue entries. If you activate it you need to define also a field to be used as Datalink ID. And,below, you will have to define what links you want to show and their properties.

Links for Datalink

In our example catalogue we have three types of links:

• Link to the SVO Filter Profile Service.
• Link to the transmission curve (ascii file).
• Link to the plot of the transmission curve (png file).
