The GUI Design Review

of WMO Product on the Text Workstation

Author: Xiangbao Jing

1.1 Basic Capabilities

Display AFOS and WMO text products.
Create WMO products

1.2 Display Processing

Querying
Selecting
Loading

(See F-1)

1.3 Display GUI

Entry bar and browsers

Entry Bar (See F-2)

AFOS command Entry, loading by using AFOS command
WMO-ID Entry, TTAAii and CCCC, loading or partial querying
AWIPS-ID Entry, NNNXXX, loading or partial querying
Time Entry, DDHHMM, loading or partial querying

browser

AFOS Browser (See F-2), Select a product ID in the ID table
WMO Browser (See F-3), select a product ID in queried header list
AWIPS Browser (See F-4), select a product ID in queried header list

1.4 Editing GUI

Create WMO header, TTAAii, CCCC, CCC, NNN, XXX, BBB and address
CCC, for user create WMO header by using AFOS ID

1.5 Interface With Text DB (WMO part)

Query and Read

WMO Command line:

textdb [-ri AwipsID] [-rt ddhhmm] [-rw TTAAii] [-rs CCCC] [-rb BBB]

textdb -rv TTAAii CCCC BBB [NNNXXX]

Returned ID format:

TTAAii CCCC DDHHMM BBB NNNXXX CCCNNNXXX\n

Unique ID, return product
Partial, return header list (fullID list) for browsers to using
ddhhmm=00000 return inventory, otherwise latest

Write

WriteTextt DB -remote datafilename

1.6 Implement Issues

Trade off the partial entry capability with text DB and GUI performance
Test the GUI performance by using a real text DB
Logical limitations are needed in entries
Full-ID Solution, Displaying the List having Mixed IDs

In 4.2, we only used AFOS-ID, everything in the text WS code is based on it. But we are changing the text WS to support the AFOS-ID, AWIPS-ID and WMO-ID at same time. There will be mixed kind of IDs in such as load history list, product command lists... How to display these lists in GUI? And how to express the different IDs internally?

My design is that to use special prefix solution and express these IDs in memory as full-ID. Here is the definition,

Product Command List::= Product Command 1, Product Command 2,

... Product Command n

Product Command ::= AFOS Command | AWIPS command | WMO command
AFOS Command ::= AFOS-prefix: AFOS-ID
AFOS-prefix ::= [E | M | [ [-] [A | ALL | n]]]
AFOS-ID ::= CCCNNNXXX
AWIPS command ::= AWIPS-prefix : full-ID
AWIPS-prefix ::= AWIPS
full-ID ::= TTAAii CCCC DDHHMM bbb AWIPS-ID AFOS-ID
AWIPS-ID ::= NNNXXX
WMO command ::= WMO-prefix : full-ID
WMO-prefix ::= WMO

Solution for displaying, internal expression is,

Cmd type                 in GUI Display                                       in Memory

AFOScmd                AFOS-prefix:CCCNNNXX                 AFOScmd

AWIPScmd              AWIPS:NNNXXX                                AWIPS:full-ID
WMOcmd                WMO:TTAAii CCCC                           WMO:full-ID
