See http://projects.arcs.org.au/trac/fullmoon/wiki/FullMoon I initially developed it in 2007 for Geoscience Australia and it was taken over and further developed by CSIRO. It's design is fairly generic but the packaged rule sets (xquery) are specific to processing XMI representations of ISO19136 UML models. Regards, Nick Ardlie Hans-Juergen Rennau talk@x-query.com Sent by: cc talk-bounces@x-qu ery.com Subject [xquery-talk] XQuery frameworks 29/01/2010 09:03 Protective Mark PM Dear People, presently I am scribbling away at a little XQuery?framework into which one may plug user-supplied queries, which pulls them into a particular larger processing model, using them as combinable building blocks. Suddenly my pen hovers in mid-air, I raise my head and, listening to the snowflakes rustling in the hedge, I wonder: probably some XQuery?frameworks already exist, and we XQuery developers might really profit from being aware of them, so that, pushing the argument to its?extreme, everytime we write a query we might immediately consider plugging it into this or that framework, to enhance its usefulness. So my *question*: would anybody like to point to some XQuery?framework into which one may plug queries in order to harvest added value,?perhaps hinting at the kind of advantage one obtains? With kind regards, Hans-Juergen Rennau PS: Before closing, one word about XProc. I would not regard the language itself?as such a framework, rather as a toolkit for creating such frameworks, implementing them perhaps as a set of?XProc documents. __________________________________________________ Do You Yahoo!?

As one of the reasons why the need is real I regard the challenge of data integration. I have a feeling that there is a remarkable?contradiction between potential and reality. XQuery has a great?potential as an integrator, what with the possibility to just *name* the resource (URI) and immediately have its structured content under your fingertips. But if the actual usage of XQuery does not yet live up to the potential, one of the reasons may be that it is difficult to set up a system of many queries to a robust whole, although the *single* queries can be written so easily and?efficiently. Put differently: it makes a great difference if the focus of integration lies within a single query, or beyond. A movement?"beyond the query":?how about a processing model just?one level above the query level, of moderate complexity, integrating the execution of single queries, for example by assigning to them properties which would allow to automate their squencing, input provision and output delivery? The XQuery spec provides for the possibility to write library modules, but it?is not possible to formulate relationships between library functions. In general, we cannot say someting "about" a function. We cannot, for example, express that a query Q has a "logical" source document D, although the actual?input is not?(or not only) D itself, but the result produced by some other query Q0, likewise logically - or perhaps literally - processing?D. A really simple XML language might? make it clear that the command "apply Q to D" would have to be expanded?by a framework into a chain:?"apply Q0 to D, resulting in R;?present Q to R". We do not have this level of abstraction which would allow for orchestrating the individual queries. The XQuery language level knows only XDM values and expressions.?I wonder if?just one?level above the language a simple, standardized processing model might not be possible, simple enough to be attractive and really?enhancing efficiency.

It's far from perfect -- it is a perl script that checks the system load average (!), and the query parameters, and then reads an xml config file, and calls up an external xquery engine based on a variable -- so I could easily switch between galax, qizx and saxon, initially, and later dbxml too.? It keeps a cache, to avoid firing up a JVM (two of those implementations are in Java) with each incoming HTTP request, and does get fairly high cache hit rates. It'd be a reasonable question, "why not use servlets", and a lot of the answer to that is that, when I wrote it, Sun's licence for Java was such that Linux distributions couldn't easily include it, and Java was a sufficient pain to set up that I avoided any architecture that depended on it.? But then I started using Saxon, and, later qizx, both of which do use Java. More recently I've used dbxml, but not on the production system, as the packaging for dbxml is even weirder than for Java, and my server has changed operating systems several times over the years. All this is a long winded way of saying, a lot of it depends on the environment.? I'm particularly interested (since I work at W3C...) in what we could do to extend standardisation "beyond the query" into more of a framework, and how, and what would be the value of that, but I think the XQuery Working Group right now does not have the resources to do that sort of work.

Some of this need is satisfied by XProc. There are some who would like to see the whole application written in XQuery and don't want to see any other language present. But to my mind, integration is often about combining and reusing application components written in different languages and different technologies, and XProc meets that need admirably.

I would position XProc two levels above XQuery, whereas?an?"XQuery-only integrator" would be only one level above. If?we could afford only one single language above XQuery, the choice should certainly be the higher alternative, opening?much larger space for integration. But remains the question: is there no need for additional integrators between the XQuery level and the XProc level? I believe that such integrators can be designed and could be useful. However, if the?small-scale integration can be done in such a generic way as to deserve standardization - this is a different question. (To explore it, a first step might?be to define possible advantages in general terms.)?Lightweight-integration language between XQuery and XProc, is it possible, yes or no, is it worthwhile, yes or no?

The nicest approach to this I have seen so far is in day's Sling framework. Basically you have a hierarchical repository of files/documents that have MIME types (multiple though), and if a request hits a file, handlers are triggered on MIME type and conditions of the request (method, headers, accept, ...). Of course they also support rewriting and path mapping, but I find the first approach nicer. If you have side effect free handlers (hello XQuery) you could also get proper HTTP cache support for free. Pointing a browser at /path/to/my/script that then does something magic (maybe even based on sessions!) feels so 1999 PHP style. However this requires some relatively application specific decisions to be taken by the framework, e.g. in xDB which metadata properties describe the MIME types. And frankly, the last time I looked I found eXists approach of calling into impure functions to manipulate sessions, headers, etc. relatively ugly. It just feels very wrong to have impurity in XQuery, at least to me. > this reminds me of a quote (which I cannot remember) that basically > says any problem can be solved with yet another layer of abstraction, > except for the problem of too many layers of abstraction.

Two purposes I can immediately think of is to organize document flow from query to query, and automated input selection for batch processing, e.g. based on document properties and selection criteria. Let me briefly expand?ideas about document flow. Imagine we introduced the concept of a "document type", not in the conventional - literal - way referring to schema and DTD, but?as an abstract component?identified by a QName?and properties; and imagine we possess a simple language for characterizing queries in terms of input and output document types (in the sense just introduced); then things can get really in motion. And note the aspect that the whole approach is very concept minded, systematically building on new kinds of components and the semantics of their properties. Practically, this can get efficient and attractive, indeed, With kind regards Hans-Juergen Rennau ----- Urspr?ngliche Mail ---- Von: Martin Probst An: Hans-Juergen Rennau CC: Michael Kay ; liam@w3.org; Nicholas.Ardlie@immi.gov.au; talk@x-query.com Gesendet: Dienstag, den 2.

But then you are using one particular implementation... And using eXist to handle incoming forms seemed to involve some weird kludgery with eval() last time I looked, although that was a while ago, and I didn't look too deeply because I'd already written my own little framework. I'd really like to see more standardization - even informally - at the level "beyond the query", because I think we (the XQuery world) are missing out on a lot of opportunities for more adoption. I don't think XProc is the answer - it might be part of an answer, especially some future putative more powerful XProc based on sequences of XDM instances and synchronization points - because then you need an XProc Framework...

I do not believe it has been considered -- generally, W3C Member organizations come to us (W3C) and propose work items; often we then arrange a public Workshop, and if that goes well, start a Working Group. Years ago I worked on an SGML Shell (never released, it used proprietary software) and tried to get some people interested.

It's also a *scripting* language. http://www.w3.org/TR/xquery-sx-10/ The XQuery scripting extension does provide control flow capabilities around queries, updates and Web function calls. It's smoothly integrated with the rest of XQuery, such that it avoids the paradigm shift that usually costs productivity and performance. (this makes XQuery a direct competitor to other scripting languages...Javascript, Ruby, etc.. and I think XQuery will be in the long term winning, but that's another story, and maybe another email) This is of course no excuse for not having a more sophisticated servlet-like framework around XQuery/XSLT for ease of Web application building. I believe XML needs some work in this area, hopefully standardized by the W3C for the benefit of all. Best regards Dana P.S. For everybody who will attending XML Prague, maybe we can have an evening of beer and discussions around this. I am looking forward to it.

There's an argument to be made for default namespaces applying in path expressions, but the time for that argument to be made was 1998.

Instead you either move the xpath outside the containing element, either as a function or a variable: let $num := count(collection("/db/quotes")/quote) return {$num} or you leave off the default namespace and generate well formed html, changing your output to xhtml as the last step in the process, using either a transform or a processor extension. -- Andrew Welch http://andrewjwelch.com Kernow: http://kernowforsaxon.sf.net/ From ricardo.queiros at gmail.com Thu Feb 4 13:14:31 2010 From: ricardo.queiros at gmail.com (=?ISO-8859-1?Q?Ricardo_Queir=F3s?=) Date: Thu Feb 4 04:40:18 2010 Subject: [xquery-talk] Absolute path of a selected xml snippet Message-ID: <6cec8a991002040514sddfbc66p24ba6b7e8ed44e43@mail.gmail.com> Hi to all, I have the following XML document in a text box: 1 2 By selecting " 1 " I want to get your absolute path XPath, ie, "/A/B [1]" You can do this using XQuery?

If your not already using XQuery in your app, I might suggest you implement this in pure java, its not that difficult. But how to do it will depend on what XML API your currently using. But if you plan on using XQuery, the first choice is to pick a Java XQuery implementation (before picking the API). The API interface (XQJ) doesn't actually provide an implementation. My personal favorite for embedded xquery in java is Saxon, www.saxonica.com And if your using Saxon I'd suggest its S9API over XQJ ---------------------------------------------------- David A.

You can also write your own XQuery in your own server. All depends what your server is and what your language skills are. There is also XSLT and XQuery based JSP libraries. If your running a J2EE server (like Tomcat) and want easy scripting with minimal (I.e. no) java coding integrated into it without having to run a separate server, you might want to consider the xmlsh Servlet code. http://www.xmlsh.org/EmbeddingServlet I'm using this, for example, to run XSLT and XQuery on a Tomcat server. One example I use is to do XSLT from a MarkLogic server by running the XML through a tomcat server via http post. ---------------------------------------------------- David A.

Try rename node $i as QName('http://www.gym.com', local-name($i)) You're trying to use the existing prefix to refer to a new namespace, and the trouble is that rename() doesn't get rid of the unused namespace node which binds that prefix to a different URI.

This output does not seem to be well-formed XML: a namespace declaration is in particular a reserved attribute, and the XML specification says that an element cannot have two attributes with the same name. Also, something from the XQuery Update Facility specification regarding the upd:rename update primitive is unclear to me: in your original document, there are no bindings at all ("empty prefix" to "no namespace" is not a binding, if I am correct). So, on the one hand, to me the query suggested by Michael Kay is (theoretically) correct and I do not understand why it raises a conflict, given what is in the specification. On the other hand, it makes sense to me that Saxon complains, for the following reason: if no error were raised when renaming an element which is in no namespace to a QName which has a namespace but no prefix (and hence introducing a default namespace binding), then namespace propagation could potentially have the side effect of modifying the QNames of the children (i.e., they would all be in the new namespace) although they are not being renamed... Or am I missing something? Thanks and kind regards, Ghislain > I tried that. This time I didn't get an error message from Saxon. However, the output is not right.

This query will be inefficient using a processor (such as Saxon-HE) that does serial search to implement $coleccion_cod-agrupa_xi/BLOQUE_CODAGRUPA[AGRUPA1=$distinct_agrupa1 and it will be much more efficient on one (such as Saxon-EE) that optimizes this expression using indexing or hash tables. As an alternative to finding a processor with a suitable optimizer, you could look for one that implements the XQuery 1.1 "group by" construct, or an equivalent vendor extension. (Again, Saxon-EE fits the bill). Or you could use XSLT 2.0, which has the convenient construct as standard.

But fn:put() does this, if his implementation supports updates. Of course, fn:put() does not allow you to specify serialization options separately for each file - if that's needed, then XSLT 2.0 is definitely a better solution.

It gives on-the-fly syntax checking with highlighted errors and mouseover explanations of error messages. It works well with Suraj Acharya's xquery-mode for Emacs. There are two parts: - a small Java command-line program which invokes the Saxon9 XQuery compiler and prints out errors and warnings - a few lines of Emacs Lisp to glue it in to flymake The command-line program uses Saxon9, but it could probably also be made to work with xqsharp with --static --explain as well. It would be nice if vendors (Saxon, XQSharp?) would take the code as an example and write their own command-line options for easy syntax checking. (For an example of this approach, see the "-emacs" flag in Ant, which formats one-per-line error messages easily parsed by Emacs users.) Save this as XQLSyntaxCheck.java in a directory you will use permanently: http://pastie.org/837838 Save this as xquery-flymake.el in your emacs directory. http://pastie.org/837869 Save the Emacs XQuery mode by Suraj Acharya file to your emacs directory. http://www.emacswiki.org/cgi-bin/wiki/xquery-mode.el To use, 1. Save the files as described above 2. Compile XQLSyntaxCheck.java. 3. Edit the xquery-flymake.el file to point to your Saxon9 installation and your XQLSyntaxCheck directory. 4. Compile xquery-flymake.el and xquery-mode.el (See note, below.) 5. Put these lines in your .emacs file: (require 'xquery-mode) (require 'flymake-xquery) Note: I found that in order to get xquery-mode automatically set for .xql files I needed to edit xquery-mode.el line 62 and change apostrope to "l". Otherwise, these features didn't take effect until I explicitly typed m-x xquery-mode. Leigh.

I am using a regular expression to test if a document number is correct. The number can end with either 'P,' '&P,' or it may not have an ending value outside of the regular number. For example, if a valid document number was 503-302, it could be 503-302P, 503-302&P, or just 503-302. The incorrect regular expression so far is: [0-9]{3}\-[0-9]{3}&P|P. This expression correctly finds 503-302P and 503-302&P, but of course fails to find 503-302. I've tried putting in other 'or' conditions at the end [e.g., |\s], but nothing has worked out.

David From jim.melton at acm.org Fri Feb 26 17:44:52 2010 From: jim.melton at acm.org (Jim Melton) Date: Fri Feb 26 16:29:46 2010 Subject: [xquery-talk] XQuery Update Facility test reports urgently needed: XQueryX and Static Typing Message-ID: <7.0.1.0.2.20100226160318.05ee6490@oracle.com> XQuery Update Facility implementors, The XQuery Update Facility version 1.0 test suite [1] is complete and the XML Query Working Group is awaiting test results from implementations of the specification [2]. We currently have adequate implementation test results to progress the specification from Candidate Recommendation to Proposed Recommendation (the penultimate stage of processing in the W3C, followed only by Recommendation). However, we do not yet have any test results from implementations that support the XML syntax for XQuery (XQueryX) or from implementations that support the Static Typing feature [4]. Both of these features have been marked At Risk [5]. A feature that has been marked At Risk may be deleted from the specification upon its publication as a Proposed Recommendation if insufficient implementation experience of the feature has been reported. The XML Query WG has determined that it will continue to solicit implementation reports through 2010-03-31 (31 March 2010) from implementations that support the XQueryX feature and/or the Static Typing feature. After that date, the WG will make a determination whether to publish a Proposed Recommendation without one or both of the features. If either of these features are important to you, your implementation, and/or your customer base, please consider submitting an implementation report (test suite results) showing the results of evaluating those features in the test suite. If you are able to generate test suite results for those features, but are unable or unwilling to submit your test results publicly (e.g., because of a corporate policy), you can submit them anonymously. If you wish to submit such results anonymously, please send them to the W3C Staff Contact for the XML Query WG, Liam Quin, at liam@w3.org. Liam will strip from the submitted results all information that can identify your organization and your implementation before incorporating them into the collected test suite results. We await your implementation reports!
