User-defined rules with SPIN (SPARQL CONSTRUCT)
Hi,
We are looking at SPIN as an alternative to define and execute user-defined rules. It is very expressive and in that point looks superior over Jena, SWRL and Oracle type of user-defined rules with IF (filter) -> THEN type of syntax. Although, SPIN is TopQuadrant's, it is entirely SPARQL, and Oracle supports SPARQL CONSTRUCT via Jena Adapter. TopBraid Composer provides and excellent tool support and rule editor for SPIN rules as well.
There is no problem to execute SPIN rules via Jena Adapter, and I believe even via TopQuadrant's SIN API, which is TopQuadrants's SPARQL based infrence engine's API.
My question is about whether Oracle has looked into supporting SPARQL CONSTUCT based user-defined rules in its native inference engine?
Do you have a recommendation for how to use SPIN based user rules in combination with Oracle inference today?
Thanks
Jürgen
Hi Jürgen,
We are actually looking into a general mechanism that allows users to plug in their own queries/logic during inference. Thanks very much for bringing SPIN up. This general mechanism is very likely going to cover CONSTRUCT queries.
To extend the existing inference engine using the existing Jena Adapter release, one possible way is as follows.
1) Assume you have an ontology (model) A.
2) Create an empty model B.
3) run performInference on both A and B using OWLPrime.
4) run SPARQL CONSTRUCT queries against A, B and inferred data
5) store the query results (in the form of Jena models) back into model B.
6) If the size of model B does not change, then stop. Otherwise, repeat 3)
Note that model B is created to separate your original asserted data from inferred data.
If you don't need such a separation, then don't create it.
Thanks,

Driving processing with user defined rules
Hi,
I am looking for some examples of user defined rules for file processing.
So I have a file loaded in to the application in a staging table, user will want to define rules to process the data and then an output will be created.
Very vague question I know but has anyone got any examples where they did something similar which might help?
Thanks.Roger,

Just so you know, this is not necessarily the best way to do what you're asking. It does get the job done however.
If you inspect the code it's basically just a bunch of string concatenation operations based on the presence or absence of each of the input parameters. Pretty much what you were asking about.

About user defined function in user defined rule
Hi,
I am wondering if I can use a user defined function in a user defined rule in oracle sem.. I've seen examples of user defined function used in sparql query filter clause in that dev. guide. However, I don't know if I can define a function in oracle sem. database and use it in the rule body or head. For example, I want to define a duration function that calculate the date difference between two dates. Then, I want to define a rule like this: event1 :has_start_date d1 and event1: has_end_date d2 and duration (24, d1,d2) then event1:date_satisfiable "yes". Does oracle support this kind of rule? Thank you very much.
HongHi Hong,
The user defined rules are quite similar to a CONSTRUCT SPARQL query, where the FILTER clause is implemented in SQL.
I think we have already written rules like you want :
You have to write a PL/SQL FUNCTION that returns a NUMBER (not a BOOLEAN, think you are in SQL) :
FUNCTION DURATION(HOURS INTEGER, D1 VARCHAR2, D2 VARCHAR2) RETURN INTEGER
IS
BEGIN
IF(.................)
THEN RETURN 1;
ELSE RETURN 0;
END IF;
END;
Maybe you will have to GRANT EXECUTE ON DURATION TO MDSYS.
Then include the following in the FILTER clause of the Rulebase "[owner].duration (24, TO_CHAR(d1),TO_CHAR(d2)) = 1"
Hope this helps. -
User defined rule for missing triples
Hi,
i would like to know if there is a way to define a user defined rule for triples that are not contained in a model. With curly brace syntax it could be something like this:
INSERT INTO mdsys.semr_validation_rb VALUES(
'test_rule',
'{?s ?p ?o. OPTIONAL{?s rdf:type ?t}}',
't is null',
'(?s <hasType> "false")',
null);
Unfortunately this is not working. Has anybody a suggestion to solve this problem with user defined rules?Hi,
This is related to the following post.
built-in primitives(noValue,remove) for user defined rules
Note that there is something you need to pay a bit attention to.
Say your original graph contains
:John :fatherOf :Mary
but not any type classification for :John (i.e. no match for {:John rdf:type ?t})
Assume you add the following triple according to the rule you described
(:John <hasType> "false")
Now, what happens if :John is classified as a :Person (or :Parent, :Father),
do you want to withdraw* :John <hasType> "false"?
Thanks,

How to use negation in user defined rules?
Hi,
Can you please show me an example to use negation in user defined rule? I created a rule like below (the rule says if a patient has a fever problem and not have penicillin hypersensitivity, then recommend medication1):
INSERT INTO mdsys.semr_myMedicineRB VALUES('rule1',
'(?p rdf:type :Patient) (?p :present ?c1) (?c1 rdf:type :Fever) (?c2 rdf:type :Penicillin_Hypersensitivity)',
'(NOT_EXISTS(p :present c2))',
'(?p :recommendation :medication1)',
SEM_ALIASES(SEM_ALIAS('','http://www.example/medicine#')));
The rule successfully inserted into the rulebase. However, I cannot pass the entailment creation phase and got the errors:
ORA-29532: Java call terminated by uncaught Java exception: java.sql.SQLException: Missing IN or OUT parameter at index:: 1
ORA-06512: at "MDSYS.SDO_SEM_INF_INTERNAL", line 16453

ORA-06512: at line 2
29532. 00000 - "Java call terminated by uncaught Java exception: %s"
*Cause: A Java exception or error was signaled and could not be
resolved by the Java code.
*Action: Modify Java code, if this behavior is not intended.
According to the post built-in primitives(noValue,remove) for user defined rules, it seems negation is not supported in user defined rules. Can you please advice how to implement negation in user defined rules? Thanks a lot in advance.
HongHi Hong,
Let's look at this similar but simplified problem:
if (?p rdf:type :Patient) and (NOT_EXISTS(?p :present :c2)) ==> (?p :recommendation :medication1)
You can use something like this in the user defined inferencing:
-- First get the numeric IDs for the relevant URIs
recomID := sdo_sem_inference.oracle_orardf_add_res('http://..../recommendation');
medID := sdo_sem_inference.oracle_orardf_add_res('http://..../medication1')
rdfTypeID := sdo_sem_inference.oracle_orardf_res2vid('... full URI for rdf:type');
patientID := ...
presentID := ...
c2ID := ...
-- Now this query will find out ?p that satisfy (?p rdf:type :Patient) but not
-- (?p :present :c2)
sqlStmt := '
select ids1.sid sub
from ' || src_tab_view || ' ids1
where ids1.pid= ' || to_char(rdfTypeID,'TM9') || '
and not exists (
select 1
from ' || src_tab_view || '
where sid = ids1.sid
and pid = ' || to_char(presentID, 'TM9') || '
and oid = '|| to_char(c2ID,'TM9') || '
insertStmt := '
insert /*+ parallel append */
into ' || output_tab || '(sid, pid, oid)
select sub, '||to_char(recomID,'TM9') || ',' || to_char(medID,'TM9') || '
from (' || sqlStmt || ')'

Decidability issue of oralce user defined rules
Hi,
Accoring to some online posts (http://weblog.clarkparsia.com/2007/08/27/understanding-swrl-part-2-dl-safety/, http://protege.cim3.net/cgi-bin/wiki.pl?SWRLLanguageFAQ), SWRL in general is undecidable.However, we can add some restrictions to SWRL to regain decidability: Variables in DL Safe rules bind only to explicitly named individuals in ontology. Adding this restriction is sufficient to make SWRL rules decidable. So, I'm wondering how Oracle user defined rules achieve the decidability. Does it adpot the way simliar to SWRL? Thanks a lot in advance.
HongHi Hong,
This is a good question. Yes we have adopted a similar idea. The forward chaining based inference engine in Oracle Database will only bind existing known RDF resources to variables in rules. We will not generate a new RDF resource that does not previously exist in the ontologies. This is very important because it ensures the inference process will finish in a finite amount of time.
The above does not apply to user defined inferencing (a 12.1 new feature) though.
Thanks,

What the best way to create User defined table with ADDON purpose
Hi folks, how are you ?
I´m beginner in development to business one, and I m studying to develop ISV addons.
But, during my exercises and analisys, I learned that have two ways to create tables and fields in business one. One way is throght by wizard in business one using Tools Menu > Configuration Tools > User Defined Tables >
Obs: I ´m using Business One Patch Level 9.
Other way, is create the tables and fields using DI API
But, my question is. When I develop one addon, or one UDO form that uses one set of user defined tables or used defined fields that where created by the first way (by wizard in B1), how I deploy this in other business one installation ? The package process will ensure the creation of this tables in another enviroment or I must implement the creation of user defined tables using DI API so that this code is called during the installation?
If in cases of addon develop I must use DI API to create user defined tables, How can I use my classes with this responsibility in package process ?
Thanks my friends.Hi Renan,
You just need to put your logic in to the startup of your application, after you've established your connection to the UI API and DI API. All this will be triggered in the constructor of your main class.
namespace MyNamespace
public class MyAddon
bool runAddon = true;
bool initialised = false;
const string ADDON_NAME = "My Addon";
public static void Main()
MyAddon addOn = new MyAddon();
if(runAddon)
System.Windows.Forms.Application.Run();
else
Application.Exit();
public MyAddon()
// Connect to SBO session for UI
if(!SetApplication()) runAddon = false;
private bool SetApplication()
// Code goes in here to establish UI API and DI API connections
// See SDK samples for examples
// You should also define and filter the UI API events your addon will trap at this stage and create any menus
// Call your routine to check if the required UDFs/UDTs exist on this company
initialised = CheckInitialisation();
if (!initialised)
// AddOn not yet intialised on this company so prompt the user to run the intialisation process
int iResponse = app.MessageBox("The " + ADDON_NAME + " addon will now create all required fields and tables."
+ System.Environment.NewLine + System.Environment.NewLine
+ "WARNING: It is strongly recommended that all other users are logged out of this company "
+ "before running this process. Are you sure you wish to continue?", 2, "Yes", "No", "");
if (iResponse == 1) initialised = InitialiseAddOn(); // Call your routine to create the objects
return true;

User defined Variable with multiple value
Hi Experts,
customer requirement is the following:
Build a layout in which to have in Lead Column the cost center characteristics, but not all cost center in master data but only those chosen by user with manual input. To achieve this goal i have created a variable of type characteristics (associatd to cost center CH) with replacement type "user defined values", then i have put this var in planning level. I have created a layout with Cost Center in Lead Column and set "all possible ch combination" in additional setting.
Thanks to the varable created, the user can enter Cost Center value, but the problem is that he cannot select more than one single cost center value, for example:
User want to see in layout CosCen1 and CosCen4, by now he can set variable in order to see the entire range from CosCen1 to CosCen4 (included all intermediate Cost Center) or to see only one between those 2 Cost Center, but it's not possible (or better i don't know how to..) to select both cost center and display the layout with ONLY those 2 Cost Center in Lead Column (CosCen1 and CosCen4).
In other word, is it possible to set a variable with more than one single value without using range from-to?
If not, does exist an alternative?
Thanks in advance.
FabioHi Fabio,
It works as follows.
let's say you have 3 multiple single lines for your cost center variable.
once you are in the folder, select any single value & the layout is ready for planning with the corresponding cost center.
now, select the "Cost center variable row" in the header of the folder within section "Name of Variable" & click on "Trash Can" icon to "Delete Selection" of variable.
this basically deletes all the entered selections (3 entries) & displays for all.
It works this way, because we don't have "resriction of values required by user".
if am not wrong & correct me if am wrong,
overall, this is nothing but equal to "planning level not restricted with any variable".
I just tested this & the flaw in this is that, it is not only displaying for all the initially entered 3 lines but it displays for each & every cost center irrespective of the variable selections.
hope it is clear. -
Oracle 11g AQ : problem enqueue user-defined type with varchar2 attribute
Hello.
I have a problem enqueuing a user-defined type to the queue on Oracle 10g.

USER_DATA.LABEL
USER_DATA.CODE 1
USER_DATA.TODAY 04.07.2008 15:30:30I must point to a strange thing: when the FixedType instance is created (via new operator) and then the setLabel("....") called as:
FixedType data = new FixedType();
// hack: proper initialization for 'label' field
data._struct.setNChar(1);
data.setId(ID);
data.setLabel(label);
data.setCode(1);
Date today = new Date();
data.setToday(new Timestamp(today.getTime()));
Datum d = data.toDatum(connection);
STRUCT s = (STRUCT) d;
logger.debug(s + ".debugString(): " + s.debugString());
logger.debug(s + ".dump(): " + s.dump());and if i comment line (data._struct.setNChar(1);) the debug messages for created STRUCT also shows empty value for label.
But if i explicitly call data._struct.setNChar(1) then debug contains the label i defined in call to the setLabel method. -
How to use user defined object with linked button
Hi experts
Can I use user defined table data with linked button. If yes then how. plz give me sample examples.
Regards
GorgeIf you have an UDO in your form, or any other, the FormDataLoad eventhandler should be used.
Take care, it is not inside the eventhandler.
for VB:
Select SBO_APPLICATION in the classes, and select FormDataLoad event
Private Sub SBO_Application_FormDataEvent(ByRef BusinessObjectInfo As SAPbouiCOM.BusinessObjectInfo, ByRef BubbleEvent As Boolean) Handles SBO_Application.FormDataEvent
in C#
Add a new eventhandler as
// declaration
SBO_Application.FormDataEvent += new SAPbouiCOM._IApplicationEvents_FormDataEventEventHandler(ref SBO_Application_FormDataEvent);
// eventhandler:
public void SBO_Application_FormDataEvent(ref SAPbouiCOM.BusinessObjectInfo BusinessObjectInfo, out bool BubbleEvent) -
Dealing with User Defined Tables with the DI Server
I have a general question about the best way of working with the data in user defined tables using the DI Server. It appears from previous posts that it is not possible to use the standard methods such as UpdateObject. Also since update/insert and delete statements or explicitly forbidden using the ExecuteSQL method then how do we interact with the data in the tables?
Do we need to code our own data access layer for this type of access and is this a good practice?
Is this type of functionality going to be available in a future release of the DI Server?
ThanksUsing SQL for Update/Insert/Delete is not forbidden on UDTs (at least non-UDO UDTs; UDO UDTs are somehow in a gray area since they carry internal fields + e.g. inserts require further manipulation in B1 tables...)...
I.e. using ExecuteSQL to add data into UDTs is OK for DI Server...

User defined field with Linked Table property
Hi All,
I know this has been posted several times but I cannot get this to work. I am trying to add a user defined field and link it to a table.
I am getting the error "The field 'Related Table' should consist of 8 alphanumeric characters with no valid or default values "
Everything I check says that the code I am using is correct. Is it possible the problem is that I am trying to connect to an SAP table instead of a user defined table. Is it possible to link a user defined field to an SAP table?
My code below:
oUserFieldsMD.TableName = "OITM"
oUserFieldsMD.Name = "SHP"
oUserFieldsMD.Description = "Must ship via"
oUserFieldsMD.LinkedTable = "OSHP"
oUserFieldsMD.Type = SAPbobsCOM.BoFieldTypes.db_Alpha
oUserFieldsMD.SubType = SAPbobsCOM.BoFldSubTypes.st_None
oUserFieldsMD.EditSize = 8
oUserFieldsMD.Size = 8
oUserFieldsMD.Mandatory = SAPbobsCOM.BoYesNoEnum.tNO
Thanks
KarenHello Karen,
you cannot link a userfield to a system table. it has to be link to a user table.
oUserFieldsMD.LinkedTable = "OSHP"
when you have error, just try to do it using the same value in the application. If you cannot do it, it means you cannot do it neither with the DI

User Defined Field with Link Type
Hi,
I am trying to create a user defined field to allow users to attach word documents to Item Master Data.
I have successfully created a User Defined Field under master data with Type: Data, Structure: Link.
It appears in the Item Master Data as I would expect. My questions relates to how to use this field. The first time I click on the field, a file browser window appears where I can select a file. Once I select the file I want I click ok and the path to this file appears in the field. The next time that I click on the field the file will open in its respective application.
My question is: How when the field already contains a path to a file do I change this path so it points to a different file.
Any help I can get on this would be greatly appreciated.
Thanks
BrianHi,
If you hold down Ctrl on your keyboard and then double click in the link it will allow you to browse to a different file.
Regards,

[eval 1.1.0.21]sort in user-defined ended with ; report produces ORA-00911
reproduce it with :
1) user defined reports --> add report --> SQL :
select * from scott.emp;2) click on the sort icon in the header of the column
the workaround is to not include the ; in the sql

prefixed!Laurent,
Please can you prefix your comments with Eval 1.1.0.21.4.1? We'll be doing regular eval releases for the next few weeks and many of the folk on the forum are still on 1.0 (15.57), so we need to try to keep queries clear.
I know what you are testing and using, but others migt not.
As for the comment: Yes, thanks - no need for ';' on any user defined reports. You'll see if you copy the shipped reports they don't have it either. Useful to note.
