(website is being terribly slow for me right now)
(edit to add something more productive: the site is littered to the tune of at least 25% and maybe even a third with junk "data", all obviously added to get the number of records as high as possible, with no regard to whether that data is either useful to anybody, is machine-readable in any way at all, or even -- in the example above -- even qualifies as "data". Data.gov.ie would be moderately interesting if all the shit in it was removed.)
The biggest numbers bump recently was ca 1600 Met Eireann rainfall records datasets from all around the country, some of them daily rainfall dating back 60 years. (Spoiler, there’s a lot of rain)
This is specifically a catalog of data sets, it doesn’t host the data except for previews, and even doing that is pretty complicated in all its glory.
Then kindly explain these

Or these
https://data.gov.ie/advanced_search?query=&texttype=anywhere...
(I'd show only the PDF-only ones but your search doesn't work.)
Oh and look two of these also contain no machine-readable data whatsoever

If you are aware of such a dataset that a public body is hosting, then it would certainly be something to include. Convincing (and helping) the public bodies to publish their data is still a big task.
The handling of the whole Eircode thing makes my blood boil, to be honest.
