@samuel34 What stops you from dumping the sync data into a file and uploading it into another server? ---

Hi, @samuel34 I can see nothing wrong in your config, but I suspect that your local instance may not be accessible from outside and thatā€™s why sync4 canā€™t access it as well. Regards, Tomasz ---

I think I was getting it wrongly. Since its in the same circles, I think its sync. ---

@dkayiwa @samuel34 Just to confirm that we are on the same pageā€¦ Below is my understanding. 1. The purpose of this project is to be able to merge patient data from multiple installations 2. The default way is to extract the patient information from each of the different tables and package it in a way that can be imported into another instance 3. However with sync2 in progress, there is a possibility to leverage this. How: - Sync currently exposes patients, observations etc into a FHIR/REST interface, but underneath all that the data is stored in tables (in case of no connection) - The idea in this case is to export the data from the sync tables and import it into another instanceā€¦ - That way the project is dependent on the sync structure, but extends it in a way that was not planned earlier @tmueller Please do add your thoughts too - I may be totally off track here ---

Sorry, just jumped in here with very little context, but it does sound like if this project could leverage sync like @ssmusoke suggests, that would be greatā€¦ I would definitely get the thoughts of the team working on Sync about this use case. Take care, Mark ---

Hi all! Iā€™m still getting myself familiar of how sync2 works by looking directly at the code base. Iā€™m atleast aware that sync uses the atomfeed module for getting aware of events in the entire platform ie. New Patient update. But I was curious of how it happens(is it through some AOP logic!). Looking at the codebase, I hit upon this [AtomFeedClient#process()](https://github.com/openmrs/openmrs-module-atomfeed/blob/master/api/src/main/java/org/openmrs/module/atomfeed/client/AtomFeedClient.java#L7) method delegated [here](https://github.com/openmrs/openmrs-module-sync2/blob/master/api/src/main/java/org/openmrs/module/sync2/client/reader/impl/LocalFeedReaderImpl.java#L51). Is that the method that checks the entire OpenMRS context for new events(Atom feeds) ? If not, could you try explain this for me or point me to related resources! cc: @tmueller , @ssmusoke , @mogoodrich and Others. ---

Yes, but the methods that trigger the whole synchronization process are: [LocalFeedWorker#process](https://github.com/openmrs/openmrs-module-sync2/blob/master/api/src/main/java/org/openmrs/module/sync2/client/reader/LocalFeedWorker.java#process()) and [ParentFeedWorker#process](https://github.com/openmrs/openmrs-module-sync2/blob/master/api/src/main/java/org/openmrs/module/sync2/client/reader/ParentFeedWorker.java#process()) Regards, Tomasz ---

Hi @ssmusoke! I think I should get started with ā€œrealā€ work on this today. #### How to get started I thought of starting with implementing service layers that retrieve the sync-able data from the entire OpenMRS context first. Could you come in here now, help me get moving by giving me directives in form of TODOs? I feel its the best way we can get moving šŸ™‚ ---

Hi ! As a starting point, I have so far focused on a Patient as a Resource. I made a [PatientResourceService](https://github.com/samuelmale/openmrs-module-mergepatientdata/blob/master/api/src/main/java/org/openmrs/module/mergepatientdata/api/PatientResourceService.java), however, this doesnā€™t have a DAO. Iā€™m thinking of just it just delegating the core PatientService [here](https://github.com/samuelmale/openmrs-module-mergepatientdata/blob/master/api/src/main/java/org/openmrs/module/mergepatientdata/api/impl/PatientResourceServiceImpl.java#L16). However, running this [test case](https://github.com/samuelmale/openmrs-module-mergepatientdata/blob/master/api/src/test/java/org/openmrs/module/mergepatientdata/api/PatientResourceServiceTest.java#L21) fails with the error below. > ERROR - Context.getServiceContext(258) |2018-05-25 04:07:20,859| serviceContext is null. Creating new ServiceContext() Could I be missing something? cc: @ssmusoke , @dkayiwa ---

BTW @ssmusoke , does this use case make any sense?

The problem was solved šŸ˜‰ But just to ask a little about openmrs-platform . Should snapshot 1.0.0 depend on platform [1.11.6](https://github.com/samuelmale/openmrs-module-mergepatientdata/blob/master/pom.xml#L70) as it is by default? Or! How do we basically handle platform compatibility? cc: @ssmusoke, @dkayiwa ---
