>Hyperwave</SPAN

<A
HREF="http://www.iicm.edu/"
TARGET="_top"
>IICM</A
> in Graz. It started with
the name <ACRONYM
CLASS="acronym"
>Hyper-G</ACRONYM
> and changed to Hyperwave when
it was commercialised (in 1996).
</P
><P
> Hyperwave is not free software. The current version, 5.5 is
available at <A
HREF="http://www.hyperwave.com/"
TARGET="_top"
>http://www.hyperwave.com/</A
>.
A time limited version can be ordered for free (30 days).
</P
><P
> See also the <A
HREF="ref.hwapi.html"
>Hyperwave API</A
> module.
</P
><P
> Hyperwave is an information system similar to a database
(<ACRONYM
CLASS="acronym"
>HIS</ACRONYM
>, Hyperwave Information Server). Its focus
is the storage and management of documents. A document can be any
possible piece of data that may as well be stored in file. Each
document is accompanied by its object record. The object record
contains meta data for the document. The meta data is a list of
attributes which can be extended by the user. Certain attributes
are always set by the Hyperwave server, other may be modified by
the user. An attribute is a name/value pair of the form name=value.
The complete object record contains as many of those pairs as the
user likes. The name of an attribute does not have to be unique,
e.g. a title may appear several times within an object record.
This makes sense if you want to specify a title in several languages.
In such a case there is a convention, that each title value is
preceded by the two letter language abbreviation followed by a colon,
e.g. <VAR
CLASS="literal"
>'en:Title in English'</VAR
> or <VAR
CLASS="literal"
>'ge:Titel
in deutsch'</VAR
>. Other attributes like a description or keywords
are potential candidates. You may also replace the language
abbreviation by any other string as long as it separated by colon
from the rest of the attribute value.
</P
><P
> Each object record has native a string representation with each
name/value pair separated by a newline. The Hyperwave extension
also knows a second representation which is an associated array with
the attribute name being the key. Multilingual attribute values itself
form another associated array with the key being the language
abbreviation. Actually any multiple attribute forms an associated
array with the string left to the colon in the attribute value
being the key. (This is not fully implemented. Only the attributes
Title, Description and Keyword are treated properly yet.)
</P
><P
> Besides the documents, all hyper links contained in a document
are stored as object records as well. Hyper links which
are in a document will be removed from it and stored as individual
objects, when the document is inserted into the database.
The object record of the link contains information
about where it starts and where it ends.
In order to gain the original document you will have
to retrieve the plain document without the links and the list
of links and reinsert them. The functions
<A
HREF="function.hw-pipedocument.html"
><B
CLASS="function"
>hw_pipedocument()</B
></A
> and <A
HREF="function.hw-gettext.html"
><B
CLASS="function"
>hw_gettext()</B
></A
>
do this for you. The advantage of separating links
from the document is obvious. Once a document to which a link
is pointing to changes its name, the link can easily be modified
accordingly. The document containing the link is not affected
at all. You may even add a link to a document without modifying
the document itself.
</P
><P
> Saying that <A
HREF="function.hw-pipedocument.html"
><B
CLASS="function"
>hw_pipedocument()</B
></A
> and
<A
HREF="function.hw-gettext.html"
><B
CLASS="function"
>hw_gettext()</B
></A
> do the link insertion automatically
is not as simple as it sounds. Inserting links implies a certain
hierarchy of the documents. On a web server this is given by the
file system, but Hyperwave has its own hierarchy and names do not
reflect the position of an object in that hierarchy. Therefore
creation of links first of all requires a mapping from the Hyperwave
hierarchy and namespace into a web hierarchy respective web namespace.
The fundamental difference between Hyperwave and the web is the clear
distinction between names and hierarchy in Hyperwave. The name does
not contain any information about the objects position in the hierarchy.
In the web the name also contains the information on where the object
is located in the hierarchy. This leads to two possibles ways of mapping.
Either the Hyperwave hierarchy and name of the Hyperwave object is
reflected in the URL or the name only. To make things simple the second
approach is used. Hyperwave object with name <VAR
CLASS="literal"
>my_object</VAR
>
is mapped to <VAR
CLASS="literal"
>http://host/my_object</VAR
> disregarding where
it resides in the Hyperwave hierarchy. An object with name
<VAR
CLASS="literal"
>parent/my_object</VAR
> could be the child of
<VAR
CLASS="literal"
>my_object</VAR
> in the Hyperwave hierarchy, though in a web
namespace it appears to be just the opposite and the user might get
confused. This can only be prevented by selecting reasonable object names.
</P
><P
> Having made this decision a second problem arises. How do you
involve PHP? The URL <VAR
CLASS="literal"
>http://host/my_object</VAR
> will
not call any PHP script unless you tell your web server to rewrite it to
e.g. <VAR
CLASS="literal"
>http://host/php_script/my_object</VAR
> and the script
<VAR
CLASS="literal"
>php_script</VAR
> evaluates the <VAR
CLASS="varname"
>$PATH_INFO</VAR
>
variable and retrieves the object with name <VAR
CLASS="literal"
>my_object</VAR
>
from the Hyperwave server. Their is just one little
drawback which can be fixed easily. Rewriting any URL would not allow
any access to other document on the web server. A PHP script for
searching in the Hyperwave server would be impossible. Therefore
you will need at least a second rewriting rule to exclude certain
URLs like all e.g. starting with <VAR
CLASS="literal"
>http://host/Hyperwave</VAR
>
This is basically sharing of a namespace by the web and Hyperwave server.
</P
><P
> Based on the above mechanism links are insert into documents.
</P
><P
> It gets more complicated if PHP is not run as a server module or CGI
script but as a standalone application e.g. to dump the content of
the Hyperwave server on a CD-ROM. In such a case it makes sense to
retain the Hyperwave hierarchy and map in onto the file system. This
conflicts with the object names if they reflect its own hierarchy
(e.g. by choosing names including '/'). Therefore '/' has to be
replaced by another character, e.g. '_'.
</P
><P
> The network protocol to communicate with the Hyperwave server is called
<A
HREF="http://citeseer.nj.nec.com/andrews95serving.html"
TARGET="_top"
>HG-CSP</A
> (Hyper-G Client/Server
Protocol). It is based on messages to initiate certain actions, e.g. get
object record. In early versions of the Hyperwave Server two native
clients (Harmony, Amadeus) were provided for communication with the
server. Those two disappeared when Hyperwave was commercialised. As a
replacement a so called wavemaster was provided. The wavemaster is like a
protocol converter from <ABBR
CLASS="abbrev"
>HTTP</ABBR
> to <ABBR
CLASS="abbrev"
>HG-CSP</ABBR
>.
The idea is to do all the administration of the database and
visualisation of documents by a web interface. The wavemaster implements
a set of placeholders for certain actions to customise the interface.
This set of placeholders is called the <ABBR
CLASS="abbrev"
>PLACE</ABBR
> Language.
<ABBR
CLASS="abbrev"
>PLACE</ABBR
> lacks a lot of features of a real programming
language and any extension to it only enlarges the list of placeholders.
This has led to the use of JavaScript which IMO does not make life
easier.
</P
><P
> Adding Hyperwave support to PHP should fill in the gap of a
missing programming language for interface customisation. It
implements all the messages as defined by the <ABBR
CLASS="abbrev"
>HG-CSP</ABBR
>
but also provides more powerful commands to e.g. retrieve complete
documents.
</P
><P
> Hyperwave has its own terminology to name certain pieces of
information. This has widely been taken over and extended.
Almost all functions operate on one of the following data types.
<P
></P
><UL
><LI
><P
> object ID: An unique integer value for each object in the
Hyperwave server. It is also one of the attributes of the
object record (ObjectID). Object ids are often used as an
input parameter to specify an object.
</P
></LI
><LI
><P
> object record: A string with attribute-value pairs of the form
attribute=value. The pairs are separated by a carriage return
from each other. An object record can easily be converted into
an object array with <B
CLASS="function"
>hw_object2array()</B
>.
Several functions return object records. The names of those
functions end with obj.
</P
></LI
><LI
><P
> object array: An associative array with all attributes of an
object. The keys are the attribute names. If an attribute occurs
more than once in an object record it will result in another
indexed or associative array. Attributes which are language
depended (like the title, keyword, description) will form an
associative array with the keys set to the language
abbreviations. All other multiple attributes will form an
indexed array. PHP functions never return object arrays.
</P
></LI
><LI
><P
> hw_document: This is a complete new data type which holds the
actual document, e.g. HTML, PDF etc. It is somewhat optimized
for HTML documents but may be used for any format.
</P
></LI
></UL
>
</P
><P
> Several functions which return an array of object records do also
return an associative array with statistical information about
them. The array is the last element of the object record
array. The statistical array contains the following entries:
<P

><P
> The Hyperwave extension is best used when PHP is compiled as an
Apache module. In such a case the underlying Hyperwave server can
be hidden from users almost completely if Apache uses its rewriting
engine. The following instructions will explain this.
</P
><P
> Since PHP with Hyperwave support built into Apache is intended
to replace the native Hyperwave solution based on Wavemaster, we
will assume that the Apache server will only serve as a Hyperwave
web interface for these examples. This is not necessary but it simplifies
the configuration. The concept is quite simple. First of all you
need a PHP script which evaluates the <VAR
CLASS="varname"
>$_ENV['PATH_INFO']</VAR
>
variable and treats its value as the name of a Hyperwave
object. Let's call this script <VAR
CLASS="literal"
>'Hyperwave'</VAR
>. The URL
<VAR
CLASS="literal"
>http://your.hostname/Hyperwave/name_of_object</VAR
>
would than return the Hyperwave object with the name
<VAR
CLASS="literal"
>'name_of_object'</VAR
>. Depending on the type of the object
the script has to react accordingly. If it is a collection, it will probably
return a list of children. If it is a document it will return the
mime type and the content. A slight improvement can be achieved
if the Apache rewriting engine is used. From the users point of
view it would be more straight forward if the URL
<VAR
CLASS="literal"
>http://your.hostname/name_of_object</VAR
> would
return the object. The rewriting rule is quite easy:
<DIV
CLASS="informalexample"
><P
></P
><A
NAME="AEN34330"
></A
><TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
CELLPADDING="5"
><TR
><TD
><PRE
CLASS="apache-conf"
>RewriteRule ^/(.*) /usr/local/apache/htdocs/HyperWave/$1 [L]</PRE
></TD
></TR
></TABLE
><P
></P
></DIV
>
Now every URL relates to an object in the Hyperwave server. This
causes a simple to solve problem. There is no way to execute a
different script, e.g. for searching, than the 'Hyperwave'
script. This can be fixed with another rewriting rule like the
following:
<DIV
CLASS="informalexample"
><P
></P
><A
NAME="AEN34332"
></A
><TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
CELLPADDING="5"
><TR
><TD
><PRE
CLASS="apache-conf"
>RewriteRule ^/hw/(.*) /usr/local/apache/htdocs/hw/$1 [L]</PRE
></TD
></TR
></TABLE
><P
></P
></DIV
>
This will reserve the directory <TT
CLASS="filename"
>/usr/local/apache/htdocs/hw</TT
>
for additional scripts and other files. Just make sure this rule is
evaluated before the one above. There is just a little drawback:
all Hyperwave objects whose name starts with <VAR
CLASS="literal"
>'hw/'</VAR
>
will be shadowed. So, make sure you don't use such names. If you need
more directories, e.g. for images just add more rules or place
them all in one directory. Before you put those instructions, don't
forget to turn on the rewriting engine with
<DIV
CLASS="informalexample"
><P
></P
><A
NAME="AEN34336"
></A
><TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
CELLPADDING="5"
><TR
><TD
><PRE
CLASS="apache-conf"
>RewriteEngine on</PRE
></TD
></TR
></TABLE
><P
></P
></DIV
>
You will need scripts:
<P
></P
><UL
><LI
><P
> to return the object itself
</P
></LI
><LI
><P
> to allow searching
</P
></LI
><LI

</P
