In looking at a media link I don’t understand what the ‘tags’ is supposed to indicate. I have a obituary linked to a person that shows 46 tags all except 1 have a type of citation. I can’t go look at them, so I don’t know what it is supposed to mean.
Adding an update as I figured out how to go look at the citation - you click on it and then click the pencil icon. I did this for 5 of them and it brings up a screen to edit the citation. But in this case, the citation is exactly the same for them. I presume the same for all 46. I’m guessing since I linked the obituary to all the people mentioned in it, that is why I get all those citations. I think that’s overkill, but maybe I am not understanding the use of the citations.
First of all, when you add a media file to RM it is not really added to the RM database in the sense of being stored inside your RM database. It is only linked into your RM database. That one media link in turn can be tagged to zero or more items in the RM database. I say zero or more rather than one or more because media file that is linked into your RM database can sometimes be unused.
A media tag is really a kind of link, but if there are several kinds of links it can be useful not to call them all the same thing. A media link is something that links to a media file on your disk. A media tag is something that links a media file to an item in your RM database such as a person, a fact, or a citation.
It’s hard to be sure without seeing your entire database, but I suspect that 45 of your 46 media tags are really tagged to basically the same citation, except that the citation has become duplicated 45 times. Starting with RM8 and continuing on through RM9, RM10, and RM11, RM supports what are called reusable citations so that you would only have 1 citation and it would be reused 45 different times. But if data is imported into RM from RM7 or from Ancestry or from GEDCOM, the duplicate citations are not set up as reusable.
Does that sound like your situation? If so, then there is an easy way to merge all the duplicate citations so that the become reusable.
You should be able to clean the Citations up by looking at the Source. It will show the # of Citations used for each Source. If they are duplicated, you can Merge them.
