My GSoC project's progress report - 05/08/2010

2010-08-05T01:34:00.000-07:00

In the past two weeks, I have done following things:

1) Complete that new UI for localizedDescription property.

2) Completed support localization for all necessary metadata classes.

The next things I need to do are as follow:
1) Do some test for my branch
2) Make necessary code review

My GSoC project's progress report - 24/07/2010

2010-07-23T22:02:00.000-07:00

In the past week, I have done following things:

1) Analyzed the "add LocalizedMetadata interface" solution, and find that there are only User class don't need description property. So maybe I will just let User class implements interface OpenmrsMetadata.

2) Communicated with devs to make a decision on a initial UI mockup for localizable description.

The next things I need to do are as follow:
1) Complete that new UI for localizedDescription property.
2) To support localization for those necessary metadata classes.

My GSoC project's progress report - 18/07/2010

2010-07-19T08:11:00.000-07:00

In the past week, I have encountered a error while I am merging trunk into my branch "metadata-localization". This error has blocked me a few days, so my schedule is delayed:-(

But, I have resolved this error, accroding to Ben's suggestion in mailing list. Thanks for his help:-)

I think this week, I should speed up!

The next things I need to do are as follow:
1) Analyze whether the solution 'add LocalizedMetadata interface' is enough, and do *not* need any modification, because it also needs to deal with description's localization.
2) Communicate with Mike and request a second code review.
3) Consider how to support description's localization.

My GSoC project's progress report - 10/07/2010

2010-07-10T08:03:00.000-07:00

In the past week, I have done following things:

1) Completed my second project presentation.

2) Completed localization support for RelationshipType's aIsToB and bIsToA properties

3) Added LocalizedMetadata interface and BaseOpenmrsMetadata super class, according to the discussion about my project from dev mailing list.

The next things I need to do are as follow:
1) Analyze whether the solution 'add LocalizedMetadata interface' is enough, and do *not* need any modification, because it also needs to deal with description's localization.
2) Communicate with my Mentor about my work till now and hope to request a second code review soon.
3) Consider in advance for how to support description's localization.

My GSoC project's progress report - 03/07/2010

2010-07-03T09:43:00.000-07:00

In the past week, I have done following things:

1) Discuss with my mentor and other devs about how to support localization for those special metadata, such as Privilege, Role, etc.

2) Update those common methods of HibernateUtil and add related unit tests for it.

3) Update project wiki page and also paste sql functions(for mysql, postgresql and oracle) into project wiki page.

The next things I need to do are follow:
1) Apply Ben's suggestion and do localization support for RelationshipType
2) Talk with my mentor about my project progress and request a code review to my recent changes(complete localization support for most metadata)
3) Prepare for my second project presentation

My GSoC project's progress report - 26/06/2010

2010-06-26T01:19:00.000-07:00

In the past week, I have done following things:

1) Talked with my mentor about the length of name column, and I decide to use 1024 as length of name column temporarily in develop phrase.

2) I have completed the optimization for HibernateUtil class, according to the comment of ticket#372. And I also send a request in comment of this ticket to ask other devs help me to review this class together.

3) I have nearly completed half of current metadata's localization support. But the left other metadata, such as Privilege, Role, RelationShip, may be need to be dealt with specially.

The next things I need to do are follow:
1) Discuss with my mentor about how to support localization for those special metadata, such as Privilege, Role, etc
2) Complete the left metadata's localization support
3) Prepare for my second project presentation

My GSoC project's progress report - 23/06/2010

2010-06-23T05:55:00.000-07:00

I am sorry that I have posted last week's progress report till today. Because my computer encounter a small problem and lost network about a few days.

In the past week, I have done following things:

1) I have attended the last week's code review call at June, 14. And address out all comments from call and other devs' personal comments.

2) I have made a part of code changes, according to the notes from code review. But here is remainly two questions need to resolve: decide on length of 'name' column, and optimization for HibernateUtil class.

3) I also resolved the previous exception "Found shared reference to collection ...". It's because that I haven't completely support all metadata's localization, this exception won't happen after I completely support all metadata's localization.

Oh, In the past week, I haven't do much work. So in the following days, I should speed up. And I also need to preserve a few time to prepare my second project presentation in July, 8.

The next things I need to do are follow:
1) Decide on the length of 'name' column
2) Complete the optimization for HibernateUtil class
3) Begin to support other metadata's localization

My GSoC project's progress report - 12/06/2010

2010-06-12T10:18:00.001-07:00

In the past week, I have done following things:

1) I have tried to move localizedName property into BaseOpenmrsMetadata, but still have a error need to resolve. It's the "Found shared references to a collection:xxx" exception.
2) I have made several discussion with other devs, about LocalizedStringSerializer's use case, now I have refacted this class and move all its methods into LocalizedStringUtil
3) I have created database convenient function for Oracle.
4) I also determinted the code review day. It's June, 14. All my written codes in branch will be reviewed in that day's code review call.

The next things I need to do are follow:

#1 Collect comments from the upcoming code review for my branch.
#2 Reading existing comments about ticket#372, discuss with other devs and make some necessary modification.
#3 I need to difine a LocalizationException, and throw it when end-user enter a too-long localized string.
#4 Continue to find the reason for "Found shared references to a collection:xxx"

My GSoC project's progress report - 04/06/2010

2010-06-04T10:59:00.000-07:00

1) Started a discussion in dev list to decide that moving localizedName property into BaseOpenmrsMetadata class.
2) Request a Code Review for all my changes done for localization of EncounterType
3) In the waiting phase for code review, I have created database functions for Mysql and PostgreSQL.
4) I also completed my first project presentation yesterday. It goes smoothly. Only one defect I think is my listen and oral english is poor, thanks to I have prepared a google doc for my presentation, so it doesn't impact my presentation a lot:-)

The next things I need to do are follow:

#1 Collect comments from the upcoming code review for my branch and also suggestion from dev mailing list
#2 Do changes, according to the information collected from #1
#3 After complete all changes, I hope I can merge all my current changes from branch into trunk to support localization of EncounterType
#4 Continue to write out the database function for Oracle

3) Complete a project plan(Timeline) for my project, Mike and me will reach an agreement on this plan later.

The next things I need to do are mockup some examples for the new editing UI of EncounterType together with Mike and get some feedback from group; reach an agreement for the final requirements and design thoughts of my project together with Mike; request a branch for my project before starting to code.

My GSoC project's progress report - 07/05/2010

2010-05-08T06:53:00.000-07:00

In the past about ten days(28.April - 7.May), I have done follow things:

1) Create a wiki page for my project -- Localization Tools
Here is the url link for this page: http://openmrs.org/wiki/Localization_Tools

Now all requirements and design thoughts in this wiki page hasn't been determined at last. Thanks for my mentor -- Mike Seaton. He has added a "Initial Design Subject To Review" section for me, and this section helped me a lot. It make me more clearly with my design thoughts.

2) Mike (my mentor) also helped me group our devs who are interested in my project to discuss and agree on the requirements and high level specification of my project. Now we have already get some review from this group.

I think the next steps for me before starting to code, are that I need to collect any helpful reviews from devs who are interested in my project, and improve my design thoughts in project's wiki page. Also I have some questions need to resolve, such as understand how to search a metadata's name in locale hierarchy, and how to design a generic UI for editing localized metadata.

Weekly Report For Project(2009-05-03)

2009-05-04T00:31:00.000-07:00

1. Things which I have done this week
        (1) Read the source code about all domain classes and some code about the report module.
        (2) Read the document about unit test framework used in OpenMRS.

2. Things which I am doing now
        (1) Reading the API doc of XStream and some specific source code about those classes which will be used in this project.

3. Question List
        (1) The form of writing the unit test for Serialization
        As i see the document and some codes about unit test in Openmrs.  I have a problem,  i think if i should write a new Testcase for every domain object?  or i can just write a new method with "@should" in the class "SerializatoinServiceTest" for every domain object?
        Ben,  can you tell me which test class i can refer to?

        (2) About implementing the feature of "@Element(data=true)"
        I think if i extends some classes of XStream and override methods in them in order to implement the feature "@Element(data=true)",  then I don't know this manner whether will break some licences in XStream?

        (3) The form through which I will do my project
        Some projects will be done in a branch or module.  And I want to know if I can directly code for my project in current core codes in Openmrs,  Or also need make a new branch for my project?

Weekly Report for Project(2009-04-26)

2009-04-26T10:09:00.000-07:00

Hi,  Ben
        I have described my current progress about project,  and question list which i have now in this report,  can you spend a little time to review it and give me a feedback,  thank you:-)

1.  Things which I have done in this week
        (1)   Read all the relative documents in wiki,   such as User Guide,  Administrator Guide,  and Developer Guide,  etc
        (2)   Read the Tutorial of Simple Framework And know about the basic API of Simple,  mainly about   @Element,  @Atribute,  @ ElementList,  etc
        (3)   See a part codes of current domain objects

2.  Things which I am doing now
        (1)   Continue reading codes of current domain objects in Openmrs.
        I want to know more information of Simple’s annotations in Openmrs by do this.

3.  Question List
        (1)   The determinate range of objects which need be serialize/deserialize by XStream?
        When I see the code in domain objects,  I find that a few classes under the package “org.openmrs” are not have the any config annotation of Simple Framework,  such as Drug.java,  Order.java,  etc.
        Besides,  several classes not in package “org.openmrs”,  such as the “Parameter.java” in the package “org.openmrs.report”,  these classes also have the annotations of Simple Framework.
        So I am puzzled with the determinate range of objects which need to serialize.   Apparently,  the range of all domain objects in package “org.openmrs” is not same with the range of classes which have annotations of Simple Framwork.

        (2)   As using XStream to serialize objects,   now I have find three places which maybe need XStream to implement and haven’t be implemented in current code of Openmrs.
        1st:   “Root(strict=false)”
        In XStream,  it just implements the feature of “Root(strict=true)”.

        2nd:   “Element(required=true)”/”Attribute(required=true)”
        In XStream,  it only implements the feature of “(required=false)”,  it doesn’t have choices to config for “(required=true)”

        3rd:   “Element(data=true)”
        In XStream,  it doesn’t have this feature as Simple.  It just put the entity label for those special letter.

        All above,  I want to know while using XStream to serialize objects,  whether need these features all the same?   Or just a part?

        Ben,   As you say,   I have look a few topics,  if want to implement feature about “Element(data=true)”,  then need to upgrade XStream,  we need to override the HierarchicalStreamWriter class.   But I am not very sure if this manner can be suitable,  because I haven’t writen any trial code.

        (3)   Which properties of Class need to be omitted and which properties of Class need to exist in XML file as the Attribute?   (just as which properties need “useAttributeFor” and “omitField” method)
        I think whether I can get the exactly information just from the current information of Simple Framework’s annotations which have been defined in OpenMRS project.

        (4)   Which classes need Converter ?
        Now as my current knowledge,  I think just those classes (which don't serialize most of their properties or have some special converting mechanism while serialize their properties) need the Converter.

        (5)   The determinate requirements for serializing objects in my project?
        Now as i see more domain objects of Openmrs,  I find a few difference between serializing using XStream and Simple in Openmrs.  Such as some properties are defined as Attribute in the serialized xml string by Simple while they are defined as Element in the serialized xml string.  I think here is a few unmatched places and we need to fix them.

        (6)   At last i want to comfirm whether email or blog is the more convenient manner to communicate between us(such as reporting my current progress and submit my current question list,  etc)  ,   Ben ? And if you think i should using blog to submit my question list,  do you consider i should put post with label "openmrs",  because i think the talk about my question is just between us is ok?   do you agree?

        For me the two manners(email and blog) is ok,  you think which is more convenient i will do which:-)

problem of my project "Serialization Service"

2009-04-22T06:57:00.001-07:00

Hi,Ben and everyone
Now,I am preparing my final proposal for project "Serialization Service".
I have encountered a problem,as follow:

Question:How I can determin the detailed information about all the domain objects of OpenMRS?Such as which properties of object need to alias, what the alias name of the domain object, which properties of object need to omit, which objects need the specific converter?
I have problem knowing about these information :-/
Ben,or everyone else,Can you give me a guide where I can get these informations or how I can get these information?
Thanks,hope you help:-)

GSoC 2009

2009-04-21T08:59:00.000-07:00

Today,I am very happy my proposal has been accepted by my mentor and OpenMRS.Hah,Now I can know more about Open Source and give my contribution to Open Source.
Yeah,Just fighting for Open Source,a so cool work~~
