If this is an import, you need to follow the OSM Import Guidelines:
osm.wiki/Import/Guidelines

On the page you linked I couldn't find a license for this data. Are you sure the data is compatible with the requirements of OSM and ODbL?

Reminder: Please check your tags for spelling mistakes! Things like "wate way", "wateway", "water way" are useless for OSM.

Please check your upload routine. 20,000 "gpx:ele=0.0" tags are useless and should not be uploaded.
The amount of nodes also suggests that these are coming from an external source and not from a "survey"?

Hi,
these buildings and plots all got very strange 'name' tags. The 'name' tag is only for the actual name of an object, not for a description or to add a label on a map.
Could you have a look and check this?

Please stop spamming the OSM database while testing your software. There is a dedicated development API for this purpose.

Hi, welcome to OSM.
These nodes don't have any common tag to describe what they are. In OSM we have to use a well-defined set of tags to allow all software and all other users to understand what they mean.
If you look at the tags without knowing what it is and without reading the changeset comment, there is no way to understand what these objects are. Here's the relevant Wiki page describing how bicycle parking is mapped:
amenity=bicycle_parking

248 points sounds like you're copying them from somewhere. What is the source, and is its license compatible with OSM? For importing data, there is a dedicated set of rules:
osm.wiki/Import/Guidelines

Hi,
you added two uncommon tags to the bus terminal: "jeep", "tricycle". What do they mean?

Hi,
you added many 'ref:insee' - however the common spelling is uppercase 'ref:INSEE'. Could you change that?

"Ein weiteres, nicht Beschreibbares Symbol befindet sich dort" - hast du ein Foto?

PLEASE put this to proper discussion and documentation before starting to add dozens of new tags. This scheme is incompatible to all the tools implementing one of the three (!) existing tagging schemes. Not even simple things like destinations in different languages are compatible to the current scheme.

Hi,
'openable' is a tag currently notin use. Barriers that can be removed are typically tagged as 'movable'.

Hi,
may I ask you for a full documentation of this tagging scheme you use since several years? Right now you're the only one who can make sense out of these tags, e.g. there are letters in the number suffixes that nobody else uses.

Please pay attention to the direction of waterways - the way in OSM has to point in the same direction as the water flows.

We don't yet have a proper scheme for such coordinates, apart from the 'utm' tag. For the moment I'd suggest to use a tag like "coordinates" including all information:

coordinates = 12345678 9876543 XYZ

XYZ would be the system of measurement, e.g. ITM (which seems to be the current version of the Irish Grid)

Hi,
could you check the recycling tags you added here? There's a list in the wiki with the tags that should be used:
amenity=recycling#Recycling

Hi,
the keys you added contain spaces and units - this is not common and doesn't follow usual tagging schemes.

I also have trouble making sense of the easting/northing - these coordinates seem to point to somewhere close to Chester, but not Belfast.

All of them, apart from
parking:left = separate
parking:right = no

Hi,
please don't add parking tags to a whole street if they apply only to a very short portion of it. In this case, no parking tags are needed on the road because all parking has been mapped separately due to the varying restriction on each part.

Please check your recent edits, there are many tags with spelling mistakes like 'sourcee' or 'water way'.

Hi,
"maxweight:left" is not a common tag - where does this maxweight apply?
