<!-- DTD for TV listings
This is a DTD to represent a TV listing. It doesn't explicitly group
programmes by day or by channel, instead broadcast time and channel
are attributes of the 'programme' element. Optionally, data about the
TV channels used can be stored in 'channel' elements.
Data about a TV programme are stored in the subelements of element
'programme', but metadata such as when it will be broadcast are stored
as attributes.
Many of the details have a 'lang' attribute so that you can
store them in multiple languages or have mixed languages in a single
listing. This 'lang' should be the two-letter code such as 'en' or
'fr_FR'. Or you can just leave it out and let your reader take a
guess.
An example XML file for this DTD might look like this:
<tv generator-info-name="my listings generator">
<channel id="3sat.de">
<display-name lang="de">3SAT</display-name>
</channel>
<channel id="das-erste.de">
<display-name lang="de">ARD</display-name>
<display-name lang="de">Das Erste</display-name>
</channel>
<programme start="200006031633" channel="3sat.de">
<title lang="de">blah</title>
<title lang="en">blah</title>
<desc lang="de">
Blah Blah Blah.
</desc>
<credits>
<director>blah</director>
<actor>a</actor>
<actor>b</actor>
</credits>
<date>19901011</date>
<country>ES</country>
<episode-num system="xmltv_ns">2 . 9 . 0/1</episode-num>
<video>
<aspect>16:9</aspect>
</video>
<rating system="MPAA">
<value>PG</value>
<icon src="pg_symbol.png" />
</rating>
<star-rating>
<value>3/3</value>
</star-rating>
</programme>
<programme> ... </programme>
...
</tv>
This describes two channels and then a programme broadcast on one of
the channels, then some more programmes. Almost everything in the DTD
is optional, so you can write files which are much simpler than this
example.
All dates and times in this DTD follow the same format, loosely based
on ISO 8601. They can be 'YYYYMMDDhhmmss' or some initial
substring, for example if you only know the year and month you can
have 'YYYYMM'. You can also append a timezone to the end; if no
explicit timezone is given, UT is assumed. Examples:
'200007281733 BST', '200209', '19880523083000 +0300'. (BST == +0100.)
Unless specified otherwise, textual element content may not contain
newlines - this is to make it easy to convert into line-oriented
formats, and to avoid the question of what exactly a newline would
mean in the middle of someone's name or whatever. Leading and
trailing whitespace in element content is not significant.
At present versions of this DTD correspond to releases of the 'xmltv'
package, which is a set of programs to generate and manipulate files
conforming to this DTD. Written by Ed Avis (ed@membled.com) and
Gottfried Szing, thanks to others for suggestions.

<!-- The root element, tv.
Date should be the date when the listings were originally produced in
whatever format; if you're converting data from another source, then
use the date given by that source. The date when the conversion
itself was done is not important.
To indicate the source of the listings, there are three attributes you
can define:
'source-info-url' is a URL describing the data source in
some human-readable form. So if you are getting your listings from
SAT.1, you might set this to the URL of a page explaining how to
subscribe to their feed. If you are getting them from a website, the
URL might be the index of the site or at least of the TV listings
section.
'source-info-name' is the link text for that URL; it should
generally be the human-readable name of your listings supplier.
Sometimes the link text might be printed without the link itself, in
hardcopy listings for example.
'source-data-url' is where the actual data is grabbed from. This
should link directly to the machine-readable data files if possible,
but it's not rigorously defined what 'actual data' means. If you are
parsing the data from human-readable pages, then it's more appropriate
to link to them with the source-info stuff and omit this attribute.
To publicize your wonderful program which generated this file, you can
use 'generator-info-name' (preferably in the form 'progname/version'
and 'generator-info-url' (a link to more info about the program).

<!-- channel - details of a channel
Each 'programme' element (see below) should have an attribute
'channel' giving the channel on which it is broadcast. If you want to
provide more detail about channels, you can give some 'channel'
elements before listing the programmes. The 'id' attribute of the
channel should match what is given in the 'channel' attribute of the
programme.
Typically, all the channels used in a particular TV listing will be
included and then the programmes using those channels. But it's
entirely optional to include channel details - you can just leave out
channel elements or provide only some of them. It is also okay to
give just channels and no programmes, if you just want to describe
what TV channels are available in a certain area.
Each channel has one id attribute, which must be unique and should
preferably be in the form suggested by RFC2838. Then one or more
display names which are shown to the user. You might want a different
display name for different languages, but also you can have more than
one name for the same language. Names listed earlier are considered
'more canonical'.
Since the display name is just there as a way for humans to refer to
the channel, it's acceptable to just put the channel number if it's
fairly universal among viewers of the channel. But remember that this
isn't an official statement of what channel number has been
allocated, and the same number might be used for a different channel
somewhere else.
-->
<!ELEMENT channel (display-name+, icon*, url*) >
<!ATTLIST channel id CDATA #REQUIRED >
<!-- A user-friendly name for the channel - maybe even a channel
number. List the most canonical / common ones first and the most
obscure names last. The lang attribute corresponds to abbreviations
mentioned in ISO 3316.
-->
<!ELEMENT display-name (#PCDATA)>
<!ATTLIST display-name lang CDATA #IMPLIED>
<!-- A URL where you can find out more about the element that contains
it (programme or channel). This might be the official site, or a fan
page, whatever you like really.
If multiple url elements are given, the most authoritative or official
(which might conflict...) sites should be listed first.
-->
<!ELEMENT url (#PCDATA)>
<!-- programme - details of a single programme transmission
A show will be exactly the same whether it is broadcast at 18:00 or
19:00, and on whichever channel. Technical details like broadcast
time don't affect the content of the programme itself, so they are
included as attributes of this element. Start time and channel are
the two that you must include.
Sometimes VCR programming systems like PDC or VPS have their own
notion of 'start time' which is different from the actual start time,
so there are attributes for that. In practice, stop time will usually
be the start time of the next programme, but if you can get it more
accurate, good for you. Similarly, you can specify a code for
Gemstar's Showview or VideoPlus programming systems.
TV listings sometimes have the problem of listing two or more
programmes in the same timeslot, such as 'News; Weather'. We call
this a 'clump' of programmes, and the 'clumpidx' attribute
differentiates between two programmes sharing the same timeslot and
channel. In this case News would have clumpidx="0/2" and Weather
would have clumpidx="1/2". If you don't have this problem, be
thankful!
To do: Some means of indicating breaks between programmes on the same
channel. The 'channel' attribute references the 'id' of a channel
element, but the DTD doesn't give a way to specify this constraint.
Perhaps there is some better XML syntax we could use for that.

People are listed in decreasing order of importance; so for example
the starring actors appear first followed by the smaller parts. As
with other parts of this file format, not mentioning a particular
actor (for example) does not imply that he _didn't_ star in the film -
so normally you'd list only the few most important people.
Adapter can be either somebody who adapted a work for television, or
somebody who did the translation from another language. Maybe these
should be separate, but if so how would 'translator' fit in with the
'language' element?

There are two ways to specify the language. You can use the
two-letter codes such as en or fr, or you can give a name such as

It happens that 'value' is used only for this sort of thing.

<!-- A country where the programme was made or one of the countries in
a joint production. You can give the name of a country, in which case
you might want to specify the language in which this name is written,
or you can give a two-letter uppercase country code, in which case the
lang attribute should not be given. For example,
<country lang="en">Italy</country>
<country>GB</country>
-->
<!ELEMENT country (#PCDATA)>
<!ATTLIST country lang CDATA #IMPLIED>
<!-- Episode number
Not the title of the episode, its number or ID. There are several
ways of numbering episodes, so the 'system' attribute lets you specify
which you mean.
There are two predefined numbering systems, 'xmltv_ns' and
'onscreen'.
xmltv_ns: This is intended to be a general way to number episodes and
parts of multi-part episodes. It is three numbers separated by dots,
the first is the series or season, the second the episode number
within that series, and the third the part number, if the programme is
part of a two-parter. All these numbers are indexed from zero, and
they can be given in the form 'X/Y' to show series X out of Y series
made, or episode X out of Y episodes in this series, or part X of a
Y-part episode. If any of these aren't known they can be omitted.
You can put spaces whereever you like to make things easier to read.
Some examples will make things clearer. The first episode of the
second series is '1.0.0/1' . If it were a two-part episode, then the
first half would be '1.0.0/2' and the second half '1.0.1/2'. If you
know that an episode is from the first season, but you don't know
which episode it is or whether it is part of a multiparter, you could
give the episode-num as '0..'. Here the second and third numbers have
been omitted. If you know that this is the first part of a three-part
episode, which is the last episode of the first series of thirteen,
its number would be '0 . 12/13 . 0/3'. The series number is just '0'
because you don't know how many series there are in total - perhaps
the show is still being made!
The other predefined system, onscreen, is to simply copy what the
programme makers write in the credits - 'Episode #FFEE' would
translate to '#FFEE'.
You are encouraged to use one of these two if possible; if xmltv_ns is
not general enough for your needs, let me know. But if you want, you
can use your own system and give the 'system' attribute as a URL
describing the system you use.

<!-- Video details: the subelements describe the picture quality as
follows:
present: whether this programme has a picture (no, in the
case of radio stations broadcast on TV or 'Blue', legal values are
'yes' or 'no'. Obviously if the value is 'no', the other elements are
meaningless.
colour: 'yes' for colour, 'no' for black-and-white.
aspect: The horizontal:vertical aspect ratio, eg '4:3' or '16:9'.

might be added later.

<!-- When and where the programme was last shown, if known. Normally
in TV listings 'repeat' means 'previously shown on this channel', but
if you don't know what channel the old screening was on (but do know
that it happened) then you can omit the 'channel' attribute.
Similarly you can omit the 'start' attribute if you don't know when
the previous transmission was (though you can of course give just the
year, etc.).
The absence of this element does not say for certain that the
programme is brand new and has never been screened anywhere before.
-->
<!ELEMENT previously-shown EMPTY>

<!-- 'Premiere'. Different channels have different meanings for this
word - sometimes it means a film has never before been seen on TV in
that country, but other channels use it to mean 'the first showing of
this film on our channel in the current run'. It might have been
shown before, but now they have paid for another set of showings,
which makes the first in that set count as a premiere!
So this element doesn't have a clear meaning, just use it to represent
where 'premiere' would appear in a printed TV listing. You can use
the content of the element to explain exactly what is meant, for
example:
<premiere lang="en">
First showing on national terrestrial TV
</premiere>

<!-- Last-chance. In a way this is the opposite of premiere. Some
channels buy the rights to show a movie a certain number of times, and
the first may be flagged 'premiere', the last as 'last showing'.
For symmetry with premiere, you may use the element content to give a
'paragraph' describing exactly what is meant - it's unlikely to be the
last showing ever! Otherwise, explicitly put empty content:
<last-chance />

has never been shown on television before - if not worldwide then at
least never before in this country. After the first episode or
programme has been shown, subsequent ones are no longer 'new'.
Similarly the second series of an established programme is not 'new'.
Note that this does not mean 'new season' or 'new episode' of an
existing show. You can express part of that using the episode-num
stuff.

<!-- Subtitles. These can be either 'teletext' (sent digitally, and

specified in the same way as for programmes.

usually a minimum age you must be to see it. In principle the same

systems for doing this, you can also specify the rating system used
(which in practice is the same as the body which made the rating).

<!ATTLIST rating system CDATA #IMPLIED>
<!-- 'Star rating' - many listings guides award a programme a score as
a quick guide to how good it is. The value of this element should be
'N / M', for example one star out of a possible five stars would be
'1 / 5'. Zero stars is also a possible score (and not the same as
'unrated'. You should try to map whatever wacky system your listings
source uses to a number of stars: so for example if they have thumbs
up, thumbs sideways and thumbs down, you could map that to two, one or
zero stars out of two. Whitespace between the numbers and slash is
ignored.

number of values, stored as the contents of elements rather than as
attributes? Because they are data rather than metadata. Attributes
are used for things like the language or encoding of element contents,
