Accessing repository from another Alf. repository: grid tech

[sergio]

Hi all.

The poblem is: how to connect two instaces of Alfresco in order to make them communicating (to create a grid architecture)?

Let me explain better!

I have two instances of Alfresco 1.4 installed in two different servers. These two installations are used by two organizations for storing their documents. I have to share all the documents (only the metadata associated to documents) between these two installations in order to build a simple GRID structure. The final goal is to create a general registry that is the result of union of all the metadata of the two Alfresco repository. So, each organization could access the shared metadata repository to query all the available data. I was thinking about creating a third instance of Alfresco and installing it in another server, but I would like to have the repository A be able to communicate with repository B not directly but across a new repository, say C.

Is there anyone who can give me some useful details in order to build this kind of architecture?

What about a GRID architecture for the future of Alfresco?

I think you meant

This is the short blurb on the roadmap that deals with federated repositories

http://wiki.alfresco.com/wiki/Roadmap#Federated_Repositories

I am very interested in your requirements.  From what you have mentioned so far it sounds that you are interested in federated search.  Are you looking for read only behaviour or the ability to modify the metadata as well?

Do you need to provide support for retrieval of content from remote sources?  I assume they are searching the metadata for some reason and eventually will want to get to the document itself.

can you tell us more?

I rdanner (but what is your name?),

sorry for late reply but I was very busy during these last days.

Yes, you are right.

I want to share all the documents (only the metadata associated to documents) among different Alfresco installations in order to build a simple GRID structure.

I have been working at an (Italian) regional project named GebbaLab since July 2005. We are interested in creating a simple grid infrastructure based on Alfresco repositories to store and manage clinical and genomics data coming from health care providers (clinics, hospitals, labs) involved in executing specific genetic tests. In particular, we are talking about microarray and SNPs experiments for DNA sequencing. Labs have to access a private space for uploading, downloading, searching microarray data files. Metadata associated to these files have to be shared among different Alfresco repositories.

So, we are interested in all the aspects you pointed out, such as:

executing federated searching;

modifing metadata;

retrieving files from all the Alfresco repositories;

I know that the Alfresco team is working for defining a federated architecture until the end of 2006, so I think I will be waiting their results.

Are you interested in the same problem? Are you working at a similar project for which you need a federated architecture? It could be interesting to share our experiences……

If you'd like I can send you a PPT of our project we have presented at Nettab2006 last July in Sardinia.

At the moment we have some collaborations with HL7 for implementing some specs into our project, too.

Best regards,

Sergio
