Database and record structure |
| 4.1 Files |
| Pr: 2 files: dbn.PDT
dbn.PDX (respectfully: data and indexes) |
En: 1 file: dbn.ENL |
| RM: 2 files dbn.RMD dbn.RMX
(respectfully: data and indexes) |
Papyrus: 2: db db.IDX
(respectfully: data and indexes) |
| 4.2 Internal
database and record structure |
| Pr: only vertical:
Database -> Record -> Fields -> Subfields (where
available: automatic and limited: names, dates,
quot;call numbers) |
En: only vertical:
Database -> Record -> Fields -> Subfields (names
only) |
| RM: only vertical: Database ->
Record -> Fields -> Subfields in names |
Papyrus: vertical: Database ->
Record -> Fields -> Subfields in names
Relational: record(s) to (record(s); keyword(s) to keyword(s);
record(s) to journal titles and keywords |
| 4.3 Horizontal
links: between databases, records, list entries |
| Pr: no ("group"
is a virtual duplication of -pointer to- records) |
En: no |
| RM: only term synonyms in the 3
indexes: they are equivalent in searching
("reference index" is a virtual duplication of
-pointer to- records) |
Papyrus: yes, between records;
between keywords;
various types of links: some built-in, others can be added; Search,
Print/Export recognize links for records on the basis of their type;
Search recognizes links for keywords on the basis of their type |
| 4.4 Hierarchical
links (es. thesaurus, mother/sons records,
text/notecards) |
| Pr: no |
En: no |
| some fields generate
indexes which are entirely derived (automatically created
and updated), cannot be directly edited. Field data and
list contents (sort of look-up) can be
"crossed" in output to replace text: string
+ alternate.txt; journal field + any journal.lst |
Term Lists can be
regarded as autonomous (see dedicated section): their
content can be imported from external text, updated from
records, directly edited. Field
data and list contents (sort of look-up) can be
"crossed" in output to replace text: secondary
title (journal) field + journal list (with up to three
abbreviations) |
| RM: no |
Papyrus: yes, between records;
between keywords;
various types of links: some built-in, others can be added; Search,
Print/Export recognize links for records on the basis of their type;
Search recognizes links for keywords on the basis of their type and
depth |
| some fields
generate indexes which are not only derived, i.e.
automatically created and updated, as they can have
indipendent entries and synonyms and can be directly
edited |
see also dedicated sections: 8
Thesaurus and 14 Term/Entry lists, authority files |
| 4.5 Ready,
predefined record structure |
| Pr: yes (workform), can
be shared among different databases |
En: yes: "reference types",
which are automatically shared among different databases
(stored in Windows system registry) |
| RM: yes (reference type), they belong
to each database |
Papyrus: yes (reference type), they
belong to each database |
4.6 Input
worksheets
1. features
2. can be modified
3. can create others |
Pr:
1: 39 workforms -with
varying fields- for books, articles, e-mail, thesis etc.;
fields bear "step" displayed name: total number
is fixed max 45; fields are identified by a number which
determinates their position: number is fixed across all
the workforms; some fields (names, titles, dates,
pages, URL, keywords, call number) have, to a
different extent, properties -such as internal coding,
indexing, output formatting, sort, searching...- that
cannot lose or transfer to other fields;
2: yes, given abovementioned constraints,
can add, delete, move, rename fields; attributes cannot
be changed
3: yes n, each is a file |
En:
1: 26 reference types
-with varying fields- for book, articles, e-source etc.;
fields bear "step" displayed
name: total number is fixed max 38; fields are identified
by the number they bear in the Generic RT which
determinates their position: number is fixed across all
the reference types (workforms); some fields (names, journal titles,
pages, URL, keywords) have peculiarities (internal
coding, indexing, output formatting, sort...) that cannot
loose or lend to other fields;
2: yes, given abovementioned constraints,
can add, delete, move, rename fields; attributes cannot
be changed
3: yes, up to three |
e.g. '5' is either
"data file" or "medium designator" or
"map type" in 3 different workforms: Data file,
Newspaper, Map; if RT "Newspaper"
-whereby 5 is "medium designator"- gets changed
to "Journal Short form" which lacks 5, then 5
stays there with its content but no name, just number and
can be edited;
no numeric fields apart from RN for sorting; internal
pub. date format, Call number for sorting; if fields
names are changed in workforms, styles are affected and must be manually fixed,
searching and global editing are not |
if a field is deleted
from RT, existing record content is put to corresponding
Generic RT field renamed;
no numeric fields apart from RN for sorting; if fields
names are changed in RT, styles are automatically updated, searching
and global editing are not affected
|
RM:
1: 35 predefined forms:
Reference
Types -with varying fields- for books, articles. e-mail,
thesis etc.; fields bear a label as "step"
displayed name: total number is fixed max 33 (5 user
defined); fields are identified by a number which does
not imply a fixed position: number is fixed across all
the RT; some fields ( names, periodical titles,
dates, pages, URL, kw) have, to a different extent,
properties (internal coding, indexing, output formatting,
sort, searching...) that cannot lose or transfer to other
fields;
2: yes, given the abovementioned
constraints, can add, delete, move, rename fields; their
attributes cannot be changed
3: no |
Papyrus:
1: 16 predefined
forms: Reference Types -with varying fields for books, articles, internet
resources, thesis etc.;
fields bear a base name which identifies them plus a RT specific
name; total number of built-in fields is 59;
Any field has got attributes as far as: type (more than 15 types:
name, year, number...),
quantity (multiple occurrences), indexing (word, phrase ... + n. of
chars per indexed word),
spell-checking, position within RT and mandatory/optional input
2: modify built-in reference types by adding user-created fields,
and changing: name, position, mandatory/optional input of fields; user
created RTs are under user's control
3: yes, can create (up to 100) new RTs and (up to 100) new fields
[which can be added to built-in RTs] |
| 4.7 Fields attributes can be
changed; can be applied to other fields |
| Pr: no |
En: no |
| RM: no |
Papyrus: built-in fields attributes
cannot be changed
(apart from: n. of chars per indexed word; spell-checking and
position within RT); attributes for new fields are entirely under user's
control until a field is created, then it cannot be altered |
4.8 Multiples
(multi-value) fields
1. present/absent
2. specific input rules |
Pr: 1: Output display recognizes names and kw;
automatic indexes recognize only names and kw; sort in subject bibliography recognizes any field, provided occurrences are
separated by: slash(es), <CR> Line Feed or semi-colon (;) in author field
2: separators for names and kw and see 1 |
En: names as for the
output (not kw); no headings sort; lists can recognize
different separators in every single field (<CR> always fine)
2: each occurrence on a new line or properly separated |
| RM: 1 names and kw (33 URL); 2 each
value is separated by a semi-colon (;) |
Papyrus: 1 authors, editors -and
their roles, publishers, places, several patents fields, keywords, pictures
... are built-in
fields defined as multiple; any newly created field can be multiple
and input, indexing, output will recognize this property;
2: each occurrence on a new line |
| 4.9 Indexed
fields for searching |
| Pr: all fields content is
automatically indexed, out of user's control; each
character (right/left truncation), word, phrase, is
indexed, without stopwords, and thus retrievable |
En: all fields content is
automatically indexed, out of user's control (apart form
QuickIndexes for kw or full-text); each character (right/left truncation),
word, phrase, is indexed, without stopwords, and thus
retrievable |
| RM: all fields are indexed for searching purposes: Authors,
Dates, Periodical
titles, kw have special indexes |
Papyrus: all fields content is
automatically made searchable; many built-in fields are indexed to improve
reterieval speed:
RN, RefID, names, dates, titles, journals, medium, publishers and
places, abstract, comment, kw; indexing for user created fields is under
user's control |
