Hi James The reason is given a few pages down from that under the screenshots - “Avoid duplicating your own metadata across multiple portals as one high quality metadata record will be ranked more highly by search engines than several similar records on different platforms” So it depends on the relative importance you place on a higher search ranking versus multiple records being returned. Hope that helps Michael Sent from my iPhone > On 30 Jan 2020, at 09:55, Peter Parslow <Peter.Parslow@os.uk> wrote: > > James, > The text under that heading identifies: > > two main types of duplication: > 1. similar or identical metadata available from multiple publishers > 2. similar or identical metadata from the same publisher, available in more than one place > > The example given is of the first one - where two organisations have published similar metadata about the same dataset. > > Your comment is in respect of the second one.
