EPUB3 Validation Error - Assertion failed: package dcterms:modified meta element mu
[ERROR]content.opf: 3,152: assertion failed: package dcterms:modified meta element must occur exactly once

Getting this on IngramSpark and similar on http://validator.idpf.org and https://www.ebookit.com/tools/bp/Bo/...epub-validator

Line 3 is

<package xmlns="http://www.idpf.org/2007/opf" unique-identifier="uuid_id" version="3.0">
<metadata xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:dcterms="http://purl.org/dc/terms/" xmlnspf="http://www.idpf.org/2007/opf" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

I do have this in line 10

<dc:date>2019-02-14T00:00:00+00:00</dc:date>

and the below thread indicated to change it to <dcterms:modified> </dcterms:modified> but that doesn't work and returns a load of errors

Shouldn't you be looking at line 3152 and not line 3? Or is that line,column?

dc:date and dcterms:modified are not the same thing. The first is the publication date. The second is the date that the EPUB was last modified. You normally will have both. The proper syntax is:

<dc:date>2000-01-01T00:00:00Z</dc:date>

and

<meta property="dcterms:modified">2011-01-01T12:00:00Z</meta>
