- SAMPLE SESSIONS
-
- In the following, a term “M:E” means entry “E” of menu “M”.
-
- • First session: Using the file “Videos”
-
- * I this session, you will retrieve information from an existing PSI file,
- using descriptors and templates. The file “Videos” contains information
- about (mostly science fiction) movies. (The texts are in German.)
-
- 1 To start PSI and load “Videos”:
- Double-click on file “Videos”, or double-click on PSI and then open
- “Videos” with menu “File:Open …”. (A card window “Video” should open on
- loading; if no such window appears, open it with menu “Schema:Video”.)
-
- 2 To search for movies of a specific category:
- a Press button “Descriptors”. In the descriptor selection window, select
- “Animation” in the list menu on the right and press “Okay”.
- (“Category:Animation” appears on the bottom of the card window.)
- b Press “Find”; since several animations are stored, a window opens that
- allows to select one of them. Select one and press “Okay” to see its full
- information in the card window. To see the next one, press “>>”; to see a
- previous one, press “<<” (repeatedly). (There are nine movies belonging to
- category “Animation”.)
-
- 3 To search for movies that belong to several categories:
- a Press “Clear” and then bring up the descriptor selection window again by
- pressing “Descriptors”. Select both “Animation” and “Science Fiction” and
- press “Okay”.
- b Press “Find” to find movies that are both animations and science fictions;
- as only one movie is annotated as such, this one is displayed immediately
- in the card window.
-
- 4 To search for movies of several categories:
- a Press “Clear” and select descriptors “Animation” and “Fantasy” in the
- descriptor selection window, select the radio button “or” (i.e. switch from
- “and” to “or”), and press “Okay”.
- b Press “Find” to find movies that are either animations or fantasies; there
- are 16 movies described as either “Animation” or “Fantasy” (or both).
- Select one; scroll through them with “<<” and “>>”.
- c In the descriptor selection window, to switch to the other descriptor
- class, select it and press “Show”, or double-click on it. Descriptor
- selections remain valid when you switch classes. Press “Clear” in the
- descriptor selection window to clear all selections. Try to find movies for
- some of your selections.
-
- 5 To search for movies by templates:
- a In the card window, press “Clear”. To look for movies directed by Terry
- Gilliam, enter “*gilliam*” in the field labeled “Director”. Press “Find”
- and select movies as before.
- b Press “Clear” and then “Pattern”, so that your previous template reappears.
- To look for movies Terry Gilliam directed in 1984, enter “1984” in the
- field labeled “Year”. Press “Find” (only one such movie exists).
- c Combine field entries to search for other movies that match your templates.
-
- 6 To search for movies by descriptors and templates:
- Combine descriptors and templates. For example, select descriptor “Science
- Fiction” and template (director) “*gilliam*” in order to look for SF movies
- directed by Gilliam. Or use the same pattern, but check “not” in the
- descriptor selection window in order to find movies directed by Gilliam
- that were not SF movies.
-
-
- • Second session: Creating a new file
-
- * In this session, you will create a new PSI file, define a new card schema,
- and then enter and describe (annotate) cards for this schema.
- (To monitor your operations, turn on logging, i.e. check “Write log” in the
- Options window.)
-
- 1 To start PSI, create a new file, and define a new schema:
- a Start PSI, and create a new file with menu “File:New …”.
- b Select “Schema:Schema”, and a dialog window “Schema” appears; enter
- “Address”, the name for your first schema, in the field “Name”, position
- the cursor to the field “Fields” and enter
- Name, 3, Title, 1, "Home:", 3, Street, 3, ZIP Code, 1, City, 2
- Press the “Add” button to define the schema.
- You just defined a schema “Address” with the fields “Name”, “Title”,
- “Street”, “ZIP Code”, and “City”, and with the additional text “Home:”.
- c Press “Close” to close the window “Schema”.
-
- 2 To add and find cards of your schema:
- a Select “Schema:Address” to open the dialog window for your schema
- “Address”.
- b Enter a sample address in the fields of the window and press “Add”. You
- just defined a new card for the schema “Address”.
- c Add more cards to “Address” by repeating the previous step.
-
- d Check if all fields of the window are empty (press “Clear” if not) and press
- “Find”. If you have entered several cards, a menu window offers all names of
- the address you defined; if only one card exists, it is displayed immediately.
- e If several cards where found, you may browse through these with the “<<” and
- “>>” buttons.
-
- 3 To define descriptors:
- a Select “Schema:Descriptors” to open the descriptor-handling window. Enter a
- new descriptor class (e.g., “relation”) in the left edit field (labeled
- “Descriptor class”) and press the “Add” button on the left. Add new descrip-
- tors for that class (e.g., “relative”, “friend”, “business”) via the right
- edit field (labeled “Descriptor”), pressing the “Add” button on the right
- after entering each term. Try and add more descriptor classes and descriptors.
- b In the list menu on the left, the descriptor classes are listed; to the right,
- the descriptors for the currently selected class are listed. Double-click on
- a class (or select one and press “Show”) to switch from class to class.
- c Press “Close” to close the window.
-
- 4 To describe your cards:
- a Back in the “Address” window, find and display one of your addresses as you
- did before.
- b Press “Descriptors”, select one or more fitting descriptors in the various
- classes for the current address and press “Okay”. (Note the terms appearing
- on the “Descriptors” line. The current address has been described (or
- annotated or indexed) with these terms.)
- c Press “Modify” to replace the old address by the new one.
- d Annotate and modify all your addresses in the same way. (For new addresses,
- you will of course add the descriptors at the time you enter the texts.)
-
- 5 To find cards by templates and descriptors:
- To find cards matching patterns, proceed as in steps 2 through 6 of the
- first session.
-
- 6 To list cards matching patterns:
- Define patterns, but instead of pressing “Find”, press “List” to list all
- matching addresses.
- (See below on how to define export procedures to list your addresses
- differently, as well as how to define import procedures to read addresses
- from other files.)
-
- 7 To save your information:
- Save you data with “File:Save”; quit with “File:Quit”.
-
-
- • Third session: Using the file “References”
-
- * In this session, you will experience card-to-card links and card-to-text
- links. Imagine you want to build a database of book references and notes
- concerning these books (two kinds of cards). Usually, you will look in your
- notes to find literature for a certain topic; once you have found it, you
- are interested in the actual bibliographic data of the books. Finally you
- might want to get an abstract or summary of the book.
-
- 1 To start PSI and load “References”:
- Double-click on file “References”, or double-click on PSI and then open
- “References” with menu “File:Open …”.
-
- 2 To test the links:
- a Open card “Book” and move the window towards the bottom or side of your
- screen. (Note that “Book” will show bibliographic data.)
- b Open card “Note”; try to move the window so that it doesn’t obscure the
- “Book” window.
- c Assume that you are interested in literature that gives advice on alcohol
- problems. Select the descriptors “Advice” and “Alcohol” in card “Note” and
- press “Find”; the only card pointing to an adequate text reference is
- displayed immediately.
- Note how the card referred to by the link in field “Ref” is displayed in
- the “Book” card.
- d Select the “Book” card and press “File”; the text referred to by the link
- in field “File” is loaded into a new text window. You can change and save
- this text.
- e Repeat step c with other “Note” cards.
-
- 3 Background:
- The “Ref” button and the automatic card-reference function are active if
- the schema contains a field called “Ref”. The link syntax is
- Schema:FirstField.
- The “File” button is active if the schema contains a field called “File”.
- The link has to be a standard Macintosh path name, which can be abbreviated
- to denote a path relative to the home folder of the current PSI file.
