About the Presentation Catalog

The Presentation Catalog stores the content that users create.

This content includes folders, shortcuts, Oracle Analytics Server objects (such as analyses, filters, prompts, and dashboards), and Publisher objects (such as reports and templates).

Guidelines for Object Names

The object name that is visible to users, such as Analysis 1, is referred to as the logical object name.

The following list provides guidelines for object names:

No restrictions exist on which characters are allowed in the logical name of an object in the catalog, provided that the characters are valid Unicode characters. The following are valid logical names:
```
Hello World
Profit / Loss
% Sales * $ Cost ~~ $ "Expense"?
```
The length of the logical object name must not exceed 256 Unicode characters.
The length of the logical path name for an object must not exceed 16000 Unicode characters.
The number of directory segments in a logical path name for an object must be not exceed 255 segments.

For example, a directory with a name such as /n1/n2/n3/n4/…./n253/n254/n255 is acceptable, while a name such as /n1/n2/n3/n4/…./n254/n255/n256 is unacceptable.
When you pass the path name of an object using SOAP, you must escape the following characters:
```
Forward slash (/)
Backward slash (\)
Tilde (~)
Asterisk (*)
Question mark (?)
```
The following logical path names are all valid:
```
/shared/test/Hello World
/shared/test/Profit \/ Loss
/shared/test/% Sales \* $ Cost \~\~ $ "Expense"\?
```
Use care when building a catalog path. It is very common to see code that assumes the forward slash (/) is always a path separator. Always verify your path code with an object name such as "Profit / Loss".

When you pass a catalog search filter using SOAP, you must escape the following characters:

Forward slash (/)
Backward slash (\)
Tilde (~)
Asterisk (*)
Question mark (?)
Caret (^)
Dollar sign (?)

The following search filters are all valid:

Hello World
Profit \/ Loss
% Sales \* \$ Cost \~\~ \$ "Expense"\?
