Create tables, saves and retrieves the.same way you do with any other system. This is not black magic, is just data :) But you need to create the bindings. In 2012 I created bindings and give them to developers of a mobile app for a company in Netherlands (Bert works in that project). The developers only had to understand the bindings, not the whole openEHR paradigm.

Step-by-step tutorial is best. I found ArchetypeSaveLoadExample.java, but I missed a lot of imported libraries. How do I find the source code for this example? David, you have to build your own kernel. There is no fully functional kernel in Java available. There are some wheels you have to reinvent. Be careful with advices in the past, they are always/often based on limited experiences, or have some company-politically background. Think for your own, that is the most important advice I can give you. You must think about: - Database-layer, you have to consider the type of database, and then a way to serialize your RM-objects to that database. - You also must consider your infrastructure, how to handle archetypes, how to validate data against the archetypes, how to communicate with GUI's, etc. - How to have a query-engine which is able to query ADL-paths. (AQL) All this is not available in open source, even good ideas how to do so are not available. There is quite a lot you have to do before you have a working OpenEHR-kernel. So, thinking in terms of displaying data on a website, is something you do not need to do coming months. In fact, that is more or less, the last step. A first step: A good study point to start with is read the Reference Model, and look at the archetypes at: http://www.openehr.org/ckm/ Try to match them, and when you have understood that, than it will become time to think about how to design your kernel. There are many good ways to do so. This list is a good place for advice, especially when you have more specific questions good luck Bert Verhees Thanks, David On Tue, Aug 6, 2013 at 8:59 PM, pablo pazos pazospablo at hotmail.comwrote: Hi Lexis, you can grab the demographic Person archetype here: http://www.openehr.org/ckm/ Then use the ADL Workbench to extract paths, and map those paths with your fields.

Dear David, Just because the proposed options both don't seem ideal at first sight, I would like to mention that I made good experiences working with an OWL representation of archetypes [1]. It took around two weeks until I could query my self-generated archetyped patient data. OWL can be queried with SPARQL based on graph patterns. The example archetypes, patient data and queries are online: http://www.few.vu.nl/~kdr250/archetypes/index.html However, there are some issues: 1) I stored the data as instances of archetypes, not as instances of the reference model. This seems most intuitive to me, but there might be some implications that I'm unaware of. 2) The ADL2OWL translator (originally developed by Leonardo Lezcano) is not feature-complete yet. For example, terminology bindings are not implemented yet. But Leonardo and me would be happy to share what we have so far, based on an appropriate open source license. It's written in Java. Best, Kathrin [1] http://www.few.vu.nl/~kdr250/publications/KR4HC2012-Semantic-Integration-Archetypes.pdf What you need to store are instances of the reference model. That is generic, it does not have fields like you mention. Those fields are defined in archetypes. That is why I advised you yesterday, take a good look at the reference model. There is a good Java-version of it, written by Rong Chen. Then take a good look at the archetypes at the CKM: http://www.openehr.org/ckm/ You need to understand the match between them, the documentation must help you. You must understand the documentation also. However, the documentation is more about the medical meaning of the generic reference model. But for you, when developing most important is to understand the technical match, that is why the Java-code -- archetypes match is good for you to understand.. Don't do anything else before you understand this part completely. You don't need to memorize it all, just understand. Memorizing comes automatically when working with it. Take your time, give yourself a week or more to do so. That is quite normal amount of time. When you have good understanding of the match between the Java-reference-model code, the documentation and the archetypes on CKM. Then come back to this list, and we can discuss how to proceed. Seref advises against building a kernel on your own, except when you do it for academic exercise. I disagree with him. I think it is quite doable, but it is not a small thing to do. But with good help and not being afraid to ask, it can be done, and quite good. But it will take a year or more. Do you have so much time? You will really need it. Pablo advises you to use a relational database. I don't think that is suitable for a good working kernel, because you cannot run path-based queries against it, but for a start it might work. -- Kathrin Dentler AI Department | Department of Medical Informatics Faculty of Sciences | Academic Medical Center Vrije Universiteit| Universiteit van Amsterdam k.dentler at vu.nl | k.dentler at amc.uva.nl http://www.few.vu.nl/~kdr250/

Hi Bert, The idea is to validate the data by using an integrity constraint validator such as http://clarkparsia.com/pellet/icv/.

But I wonder, excuse me if it is an obvious question (I must study it, it is a lot of information, and I will depending on these questions) Is there a way to use the archetype-ADL-code as a source for automagically to a validating source for validating datasets? Not only the leaf values, that is the easiest part, but also the structure, occurrences, cardinality, illegal properties, etc? And I have another question also, I am not educated in graph-pattern, I should have been, but a day only has 24 hours. Can it be used for automagically translate AQL-queries, is that possible? Automagically means for me: can there be written software to do so. - I am interested, at this moment I am doing something similar, but still completely different. I have the data in XML, very much like defined in the OpenEHR XSD's, and I validate them with ADL translated to RelaxNG/Schematron XML offers XQuery to query the data on difficult queries, and the software to query is on the shelf (many XML-databases supports xQuery, commercially and opensource) RelaxNG/Schematron offer a way for without any tricks, translate all quirks of ADL, and validate XML with it (software is also on the shelf available, also commercially and opensource) Thanks in advance for enlightening me.

Hi Bert, I have the need to clarify some of your assertions about my previous messages: Pablo advises you to use a relational database. That?s not true. I supposed David were working with relational, but he didn't confirmed that. openEHR persistence should be DBMS independent, so I'll never advise to use relational over other thing without knowing requirements. DBMS option should depend on requirements. (e.g. how data will be used / consumed). Also, there are different level of persistence needed: for local systems, shared/federated systems, mobile and cloud based. For local systems and some shared systems, I would recommend relational. Maybe also for mobile persistence on the device. For other kinds, I'll suggest XML/JSON based DB. And for some applications, I would recommend EAV or path-value.I know some of those are different from your solution, but that is not mean that are not suitable for a huge space of solutions. I don't believe in one-fits-all solutions. IMO, this doesn't give David the answer he needs. Is good to give him options. Consider he's on a learning process. I don't think that is suitable for a good working kernel, I'm not talking about a kernel, I'm talking about persistence. One architect can put that layer on a kernel or as a service on the cloud, depends also on requirements. because you cannot run path-based queries against it, but for a start it might work. That's not true. Anyone can run path based queries against any type of DBMS, relational included. You just need a query transformer as recommended by AQL articles. -- next part -- An HTML attachment was scrubbed...

I supposed David were working with relational, but he didn't confirmed that. OK, no hard feelings about that. I must have misunderstood. I apologize. openEHR persistence should be DBMS independent, so I'll never advise to use relational over other thing without knowing requirements. *DBMS option should depend on requirements. (e.g. how data will be used / consumed).* One of the requirements is that it must be able to run path based queries. * * Also, there are different level of persistence needed: for local systems, shared/federated systems, mobile and cloud based. For local systems and some shared systems, I would recommend relational. Maybe also for mobile persistence on the device. For other kinds, I'll suggest XML/JSON based DB. And for some applications, I would recommend EAV or path-value. I know some of those are different from your solution, but that is not mean that are not suitable for a huge space of solutions. I don't believe in one-fits-all solutions. I did not advise a solution to David, I just said that a relational database could be good for starting, but would not be suitable for a full featured OpenEHR database. I recommended against a relational database. IMO, this doesn't give David the answer he needs. Is good to give him options. Consider he's on a learning process. I don't think that is suitable for a good working kernel, I'm not talking about a kernel, I'm talking about persistence. One architect can put that layer on a kernel or as a service on the cloud, depends also on requirements. because you cannot run path-based queries against it, but for a start it might work. Service, cloud, in the end, it must go to a disk, that is the part I am talking about. You can leave this decision to others, cloud, architect, service-providers, but somewhere this decision must be made. That's not true. Anyone can run path based queries against any type of DBMS, relational included. You just need a query transformer as recommended by AQL articles. Yes of course it is possible, but when talking about relational, it needs a layer which transforms from AQL to a Codd optimized database. In fact, it will be a transformation from AQL to SQL into a RDBMS schema. I don't think it is even possible for a few programmers to write that. So that solution is for me out of the question. In your case, as you state it, you want the cloud to solve it, or somewhere else where the architect (whoever that may be) puts it. That is fine. I want to solve it myself, with the people I work with. I think that is where the money is. In the solving of the technical problems. That is what I am discussing. There is no need to interfere in that discussion if you don't want to regard that as your problem. But if you do want to regard it as a situation you want to handle, then I am very pleased, if you explain/discuss how you are planning do it.

I am pretty good at Java development. But there are two many documents for a prototype. Can you send me a mapping text file and tell me all steps I should take to retrieve and save data into database? I have already downloaded openehr-aom, openehr-ap, openehr-dao, openehr-rm-core, openehr-rm-domain, adl-parser and adl-serializer packages. If you can give me a whole flow, that will be big helpful.

This is not black magic, is just data :) But you need to create the bindings. In 2012 I created bindings and give them to developers of a mobile app for a company in Netherlands (Bert works in that project). The developers only had to understand the bindings, not the whole openEHR paradigm.

Hi! On Wed, Aug 7, 2013 at 3:21 AM, Lexis Nexis lexisnexis5490 at gmail.com wrote: Is there a tutorial book I can purchase or some examples? Step-by-step tutorial is best. Skim through the document http://www.openehr.org/releases/1.0.2/architecture/overview.pdf to get an overview then go back to that and other documents for more detail when needed. Also there are some videos at http://www.openehr.org/resources/learning_centre if you prefer watching over reading. If you don't mind using alpha-versions of work in progress, then feel free to do some openEHR hands-on experiments using https://github.com/LiU-IMT/EEE described in the paper http://www.biomedcentral.com/1472-6947/13/57 (Appendix B at http://www.biomedcentral.com/1472-6947/13/57#sec9 is a very compact openEHR intro, perhaps too compact.) I hope the instructions at https://github.com/LiU-IMT/EEE/wiki/install helps you get it up and running. Try running and modifying AQL queries on the provided example content for example.
