We are using embedded gate in our service which is used for annotating documents. In this once we annotate a word it updates either a gazetteer or ontology. When we reload the document the newly added word should not be shown in the orphan list. For this we are re initializing processing resources while reloading the document. The issue we are facing is that if the word is added in gazetteer then it works properly and does not get shown in the orphan list but the word is added in the ontology then re initializing processing resource does not take the modified ontology instead it processes with the same ontology hence showing newly added word in orphan list. Can someone suggest how can embedded gate refer to modified ontology while executing the application?
Have you tried option with Factory.deleteResources? From my experience this is only one options sometimes.

I would like to build versioning for my django models. I have already tried django-reversion but i think that is not good for my use case and i have problems with many-to-many through models and multi table inheritance.
My use case:
I have a multi tenant web app. Every tenant have their own pool of resources. The tenants can create documents and reference to the resources.
Here is a simple diagram:
Now on every update from the document or a resource that is referenced in the document i would create a version of the document.
So the version should show all changes of the document and the referenced resources.
But on revert to a version only the direct values of the document should reverted and not the resources.
For example a document:
Now i edit the document and delete the resource_1 with the id 1. Also i change the name from the resource_1 with the id 2.
When i revert this document to the first version, it should look like this:
But how can i achieve this?
I think i can use MongoDB to store complete version of a document as serialized json data on every update. And can create a signal for the resources if it changed and check the correspondent documents to create also a version for the document.
Then i create for each tenant a new collection in MongoDB.
The resources itself should also have a versioning and also other models in my webapp but for the example that is not important.
I have a requirement to capture session level details like session start time, end time, src success row, failedrows etc.. in a audit table. As all those details are available in prebuilt session variables i need to store these in a table. As of now what i am doing is, taking an assignment task in a workflow and assigning all these prebuilt session variables values for a particular session to wrkflow variables and passing these workflow variables to mapping variables using another non reusable session (the mapping which loads the table) using pre variable assignment option.It is working fine for workflow which is having one session. But if i have to implement this for a workflow having more no of sessions this process will be tedious as i have to create assignment task for each of these sessions and need to create non resuable session which calls a mapping to load into audit table.
So i am wondering is there any alternative solution to get this job done? I am thinking of a solution in which if we can able to captures audit details of all session in a file and pass this file as a input to a mapping to load this data at once into table. Is this possible? any solution?
Check this out: ETL Operational framework
It covers and end-to-end solution that should fit your needs and be quite easy to extend if you have multiple sessions - all you'd need to do is apply similar Post session commands before running the final session that loads the stats to database.
I have been working on a DJANGO back-end which main use case would be the capability to store a given set of pictures with its related tags.
The current design foresees dedicated REST-ful APIs for creating a new set, adding a picture to a given set and associating tags to a given set : this results into distinct client calls.
For instance :
BEGIN the "create new set" transaction
create a new set and receive the set ID
upload the first picture of the set
upload the second picture of the set (And so on depending on the total number of pictures...)
Add the tags related to this newly added set
END the transaction
How can I commit/rollback such a transaction knowing that it is split among different HTTP requests ?
Am I having a design issue here ? Shall I favor a single cumulative HTTP request approach ?
Please take into account that such a back-end is to be used with mobile devices which might suffer from temporary signal loss.
Any advice is welcome.
UPDATE:
Would it be convenient to use model versioning packages such as django-revisions to solve the issue ?
I am using Microsoft Synch Service Framework 4.0 for synching Sql server Database tables with SqlLite Database on the Ipad side.
Before making any Database schema changes in the Sql Server Database, We have to Deprovision the database tables. ALso after making the schema changes, we ReProvision the tables.
Now in this process, the tracking tables( i.e. the Synching information) gets deleted.
I want the tracking table information to be restored after Reprovisioning.
How can this be done? Is it possible to make DB changes without Deprovisioning.
e.g, the application is in Version 2.0, The synching is working fine. Now in the next version 3.0, i want to make some DB changes. SO, in the process of Deprovisioning-Provisioning, the tracking info. gets deleted. So all the tracking information from the previous version is lost. I do not want to loose the tracking info. How can i restore this tracking information from the previous version.
I believe we will have to write a custom code or trigger to store the tracking information before Deprovisioning. Could anyone suggest a suitable method OR provide some useful links regarding this issue.
the provisioning process should automatically populate the tracking table for you. you don't have to copy and reload them yourself.
now if you think the tracking table is where the framework stores what was previously synched, the answer is no.
the tracking table simply stores what was inserted/updated/deleted. it's used for change enumeration. the information on what was previously synched is stored in the scope_info table.
when you deprovision, you wipe out this sync metadata. when you synch, its like the two replicas has never synched before. thus you will encounter conflicts as the framework tries to apply rows that already exists on the destination.
you can find information here on how to "hack" the sync fx created objects to effect some types of schema changes.

Lets say I have one table "User" that I want to synch.
A tracking table will be created "User_tracking" and some synch information will be present in it after synching.
WHen I make any DB changes, this Tracking table "User_tracking" will be deleted AND the tracking info. will be lost during the Deprovisioning- Provisioning process.
My workaround:
Before Deprovisioning, I will write a script to copy all the "User_tracking" data into another temporary table "User_tracking_1". so all the existing tracking info will be stored in "User_tracking_1". WHen I reprovision the table, a new trackin table "User_Tracking" will be created.
After Reprovisioning, I will copy the data from table "User_tracking_1" to "User_Tracking" and then delete the contents from table "User_Tracking_1".
UserTracking info will be restored.
Is this the right approach...
This is my scenario: I need to copy files to a sharepoint document library using its web services and set metadata on them. That's all possible with CopyIntoItems (from Copy webservice) except for Lookup fields. CopyIntoItems ignores them, so i need another way to set data on those fields.
I've tried to create a list item with the mandatory and lookup fields metadata and then, using the item ID (creating a FieldInformation field with the ID, as well as some other simple metadata), called the CopyIntoItems method and, instead of updating the item, sharepoint created a new one.
I can't do this in the reverse order because i have no way to get the ID from the item created by CopyIntoItems...
So, the question is: How can i upload a file to a sharepoint document library and set all its metadata? Including Lookup fields.
Use a regular PUT WebRequest to to upload the document into the library
Query the document library to find the ID of the item you just uploaded (based on path)
Use the Lists.asmx web service to update the document metadata
Helpful link: Uploading files to the SharePoint Document Library and updating any metadata columns
Keep in mind that if the destination folder item count + the ancestor folders item count exceeds the list view threshold then you can't query the list for the id (step 2 from Kit's answer).
Queries can be done more efficiently if constrained to a particular branch in the folder hierarchy. A workaround would be to modify the site settings, but the queries would be sluggish and would make the solution less portable because the threshold for Office365 and BPOS can't be changed.
