Maybe you could give an example of why you would read the Dict for an
upload.
Since one of my free tools has already come up in the discussion :)
For my various versions of IMPORT (including BCI.IMPORT) dictionaries are
used for two reasons:
1. to identify which fields to update in each source, so it can be used like
a regular verb.
2. to handle calculated fields that may also need to be inserted based on
the import data.
Here's the usage for BCI.IMPORT to give an idea:
BCI.IMPORT
--
BCI.IMPORT by Brian Leach
Import SQL data into Universe.
Syntax
--
BCI.IMPORT [FROM datasoure]
[AS username][PASS[WORD] password]
[EXEC statement|{TEXT|SQL} statement]
[PARAM parameter..]
[FIRST rows]
UPDATES filename
[FIELD] fieldname {$n|EXPR expression|@special|'value'}
[CONV code][{NUMERIC|DATE|TIME}]
[LIST 'xxx,xxx'][RELATES file][BETWEEN n AND m]
[PATTERN xxx][operator][REQUIRED]
[MAP 'code=value[,code=value]']
[UPDATES filename ...]
Operators:
--
{INSERTFIRST|INSERTLAST|INSERTPOS|INSERTAL|INSERTAR|INSERTDL|INSERTDR|ADD|SU
B}
Expressions:
EXPR[ESSION] 'Expression'
Expression is made up of:
numbers eg 1.23
operatorseg +
dictionary names eg SURNAME
uV Basic functions eg FIELD()
@Variables eg @UserNo
import column $n eg $2
eg. EXPRESSION TRIM($1:' ':$2:' ':$3)
EXPRESSION $1 * PRICE
EXPRESSION SUM(LINE_TOTAL)
Specials:
-
{@USER|@DATE|@TIME|@LOGNAME|@IMPORTFILE|@WHO|@ROW}
Example:
BCI.IMPORT FROM mysource
AS sa PASSWORD admin
EXEC 'sp_getData' PARAM 'OPEN'
UPDATES FILE1
FIELD @ID $1 NUMERIC
FIELD DATE @DATE
FIELD NAME EXPRESSION '$3: :$4'
FIELD CODE $9 LIST 'ACA,ACB,ACC'
UPDATES FILE2
FIELD @ID $4
FIELD ENTRIES $1 INSERTLAST
FIELD QTY $7 INSERT BETWEEN 0 AND
FIELD TOTQTY $7 ADD
I write a lot of my utilities to be re-usable in this way, to be used as
verbs.

You would use the dictionary item to know WHERE to put the data in U2
which file, attribute etc. if you are talking multi-values (or
deeper) then this could also be driven from the dictionary, which would
provide you with the capability of performing some mapping
UNLESS
you are in the position to dictate the format of the file you are trying to
import (aka upload?) into UV.
But, if you wanted to be able to map an arbitrary data source, as suggested
by George, using a dictionary would allow you to achieve the result in a
point click manner -- and depending on the dictionary could also ensure
that you don't download incomplete or invalid data into an otherwise
(hopefully) clean environment, setup defaults etc

I'm confused about your mention of Dict items because I don't see how you
use Dict items for Uploading. I see how you use them for Downloading.
Maybe you could give an example of why you would read the Dict for an
upload.
