Sigil 9.5

[crutledge]

The following is my html metadata:

  <title>The Flower of Gloster</title>
  <meta content="Thurston, Ernest Temple" name="dcterms.creator">
  <meta content="2016/05/19" name="dcterms.date.of.publication">
  <meta content="Ebook prepared by crutledge@knology.net" name="dcterms.Description">
  <meta content="en" name="dcterms.language" scheme="DCTERMS.RFC4646">
  <meta content="Public Domain" name="dcterms.rights">
  <meta content="Fiction" name="dcterms.subject">
  <meta content="The Flower of Gloster" name="dcterms.title">
  <link rel="stylesheet" type="text/css" href="main.css">
</head>

The following are the errors I get from Sigil 9.5

date value '2016/05/19' is not valid as per http://www.w3.org/TR/NOTE-datetime: [For input string: "2016/05/19"] is not an integer

attribute "opf:scheme" not allowed here; expected attribute "id" or "ns:type" (with xmlns:ns="http://www.w3.org/2001/XMLSchema-instance")

I really don't understand!!!

Where are you getting these errors from? Is this from running Flightcrew after importing your html? Or is this from running epubcheck?

If so, run the GUI metadata editor and fix things.

1. HTML metadata is pointless, because there aren't any apps that actually read them; metadata should only be defined in the .opf file.

2. All your entries are missing the final slash or a closing </meta> tag:

<meta content="2016/05/19" name="dcterms.date.of.publication" />

or

<meta content="2016/05/19" name="dcterms.date.of.publication"></meta>

I agree about html metadata but Sigil will try to read it and will try to use it to set some of the opf metadata information if it can.

And yes, this is not valid xhtml. The meta tags in xhtml are void tags (empty and self closed).

And here is the spec on true metadata date-time formats from the w3c:

http://www.w3.org/TR/NOTE-datetime

Spoiler:

Exactly the components shown here must be present, with exactly this punctuation. Note that the "T" appears literally in the string, to indicate the beginning of the time element, as specified in ISO 8601.

Year:
YYYY (eg 1997)
Year and month:
YYYY-MM (eg 1997-07)
Complete date:
YYYY-MM-DD (eg 1997-07-16)
Complete date plus hours and minutes:
YYYY-MM-DDThh:mmTZD (eg 1997-07-16T19:20+01:00)
Complete date plus hours, minutes and seconds:
YYYY-MM-DDThh:mm:ssTZD (eg 1997-07-16T19:20:30+01:00)
Complete date plus hours, minutes, seconds and a decimal fraction of a
second
YYYY-MM-DDThh:mm:ss.sTZD (eg 1997-07-16T19:20:30.45+01:00)
where:

YYYY = four-digit year
MM = two-digit month (01=January, etc.)
DD = two-digit day of month (01 through 31)
hh = two digits of hour (00 through 23) (am/pm NOT allowed)
mm = two digits of minute (00 through 59)
ss = two digits of second (00 through 59)
s = one or more digits representing a decimal fraction of a second
TZD = time zone designator (Z or +hh:mm or -hh:mm)

In other words: replacing this

  <meta content="2016/05/19" name="dcterms.date.of.publication">

  <meta content="2016-05-19" name="dcterms.date.publication"/>

And then reimporting that into a new ebook should fix at least that first error message.
But again, it would probably be best to use the GUI Metadata Editor tool to fix thigs there which is the only place either FlightCrew or epubcheck will look to see if things are correct.

Still not sure what the second error message is about. Can you go to the content.opf Tab and copy the metadata section and paste it here. That should help me to see what is going wrong.
