for details of which fields are expected for which features, see
the list of feature types.
- The area the road is in, in a suitable form for use in
constructing a filename.
- The area the road is in, in a form suitable for displaying.
- For roads, or other features within an area, this describes
where in an area this road appears. There may be several of
these in one data file, if, for example, a road spans several
areas. Each of them must be on one line, without quotes, and is
of the form
area,x,y,w,h,type,link,name where the
comma-separated fields are used to place the road in a grid for
that area, the grid co-ordinates starting at the top left at 1,1.
This line has a slightly different syntax in some files included from area files: all the
layout lines from the roads and so on in the area are collected
together into one multi-line field, in each line of which the first
- The name of the area (in the form used for constructing filenames).
- The horizontal position of the left-hand end of the
- The vertical position of the top end of the road.
- The horizontal length of the road.
- The vertical length of the road. Note that if horizontal
and vertical lengths are given, the road fills a
rectangle, rather than going diagonally. To make a road
that turns a corner, give it two separate layout entries.
- The type of the feature, such as
- The link name of the feature, as used in constructing filenames.
- The displayable name of the road.
area, is not present; the first line of
this multi-line field is of the form
w is the width of the whole grid for the area, and
h is its height. These files are generated by a
script, layout-areas.html, and
for most purposes, most users and editors shouldn't need to
- The colour in which to draw the background of cells
displaying this entry. If an entry does not indicate a colour,
graphics.attr is searched, as for the
graphic field. The colour (whether
from the individual entry, or from
is then looked up in
colour.attr to get the colour
in the desired format, normally the
used by some web browsers.See also documentation on the graphics file.
- The depth of this entry, that is, how far back from the road it
extends, in units of one average house, in presentation on some
forms of output. It may sometimes be ignored.
- a free-format description of the feature; any html body markup
apart from table constructs may be used but headings and rules
probably aren't a good idea. (Table constructs are disallowed
because entries are typically shown within tables, and not all
browsers can do recursive tables.)
- which side of the road (as displayed) the feature is on. can be any of:
Each entry extends down the page until there is another entry
in the same column, that is, the same direction and the same rank (the rank defaults to 1). Thus, if you
have an entry to the left, for example, followed in the file by
several to the right, the one on the left will extend to be
opposite all those on the right.
- the times at which a regular event happens, in 24-hour format
with a dot or colon between the hours and the minutes, and, if
different on different days of the week, preceded by at least
the first three letters of the day name in english, joined to
the time by a colon. for example,
sunday:09:30. if multiple times are given, they
should be separated by commas or semi-colons.
- the fax number of the feature, given in full
- The name of a picture file from the
directory; it will have
.gif appended to it. This
is used by
getplan.cgi when the field
graphics=on is given. If an entry does not specify
a graphic, the file
graphics.attr is searched,
first for an entry matching the
variety, then, if there were no
matches of that, the
if none matching that, the
type. See also documentation on the
- A seventeen-syllable poem describing the entry, in Japanese or
A haiku contains
five, then seven syllables
and ends with five more
- the url of the feature's own home page.
- the name of an attribute file in the directory for this
type of entry (as for
link fields) which gives more detail
for this entry. this should be particularly useful for entries
that are on more than one street (for example, things at street
corners). field data in the detail file (of which only the head
entry is read) overrides fields of the same name in the initial
road file from which the
include was done.
- if this entry also has a
.attr file of its own in
this database, this names the file. the feature type and
"s/" is prepended; so for example
refers to the file
- The maximum number of rows over which this entry may spread
- a text string naming the object, in the form by which it will
normally be referred to, for example
station. please do not include html anchors in this, as
it may be used within anchors.
- The building number along the road; for example, for CB1 this is
number="32" as our address is 32 Mill Road.
- a series of ranges of times, each time being given as in
event-times fields, the times being
paired with dashes, and the pairs being separated by commas or
semicolons. for example, a shop which is open at the same times
every day of the week and which closes for lunch could be given
- what the shop, company or whatever provides.
- the religion of a place of worship.
- a string used to group things together. all features with the
same tag on the same road are taken to be at the same place
along the road. this may be used, for example, to indicate
which side-roads join at the same junction.
- the telephone number of the feature, given in full
- more detail for the type, for example, the stage of education
at an educational institute. this will normally be one of:
or may be several of these, separated by commas or semi-colons.

variety. Kinds are a finer categorization
- The length of this entry along the road, in units of one
average house. This can be used to stretch entries which don't
have several entries opposite them, in presentation on some
forms of output. It may sometimes be ignored: in particular, it
may make use of table cell or row attributes that not all
browsers will understand. Also, of course, the entry may be
drawn longer than this, because of being stretched by things
across the road from it.
- The URL of a review of this entry (usually for restaurants,
cafés and pubs).
- the type of the feature, as chosen from the available feature types
list. this field has the letter
s appended to its
value to make the name of the directory in which to find the
.attr file. to
