Help on Collections and Collection Lists
Hyperwave supports hierarchical structuring of all the objects stored
on a Hyperwave Server, much like files are stored in a
file system. What you would call a directory in a file system is called a
collection in Hyperwave. Collections can contain other collections or
documents of different types.
The following collection types are defined:
- Plain collections offer users a list
of items (or menu) to choose from. The items are the so-called
children of the collection. The order of the menu items is
determined by the SortOrder of the collection.
- Sequences are specialized collections, where the
children are treated as a sequence of documents, i.e. additional
navigation buttons are dynamically inserted between the children (see
help on sequences).
- Clusters are compound documents, i.e. the
children are shown together, but only one per document type (chosen
based on user's preferred language).
- MultiClusters combine all of their elements
(regardless of language) into a single HTML document. This is useful
for dynamically creating documents from small parts. As always, the
SortOrder and access
rights are taken into account!
- AlternativeClusters can store different
representations of documents (e.g., HTML, audio, PDF) or different
qualities (e.g., from small black and white to large 24-bit color
images) in the same cluster (i.e., under the same URL). The server
chooses which document to transmit based on user's settings in their
user records and default values.
Collection Lists
These are the icons that are used when an object is shown in a collection list:

 HGI document |
 HGI collection |
 PDF (Acrobat) document |
 MS Word document |
 MS Excel spreadsheet |
 MS Powerpoint presentation |
 Unknown object |
 Query object |
The  icon provides you with all attribute information for the corresponding object of the collection.
If an object in a collection listing is a collection, the number of documents
it contains is displayed next to it. If it is a document, its size in bytes is
displayed.
Documents and collections automatically have a "new" icon displayed next to their title
on the day they are created in Hyperwave and objects which are modified have an
"updated" icon next to their titles. Javascript is required to use this feature.
