Dear members, I need to know if the prototypes described here [1] are available at BaseX package. Using the lastest version, I can distribute the database and queries with HTTP/REST functions in a collection, but I don't know how to execute a parallel query on a single document database replicated in N nodes of a cluster. My main idea is to reduce the total query time using only BaseX implementation (or any lib compatible).

Validate module and catalogs
by France Baril 20 Jun '16

20 Jun '16

I created an entire process for my xquery to read a catalog that is built from multiple catalogs (<nextCatalog/>) so I can find the correct schema to validate my XML topics based on the schema reference (My XML files don't all use the same schemas) <topic xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance" xml:lang="en-us" class="- topic/topic " xsi:noNamespaceSchemaLocation=" urn:oasis:names:tc:dita:psd:ditabase.xsd:1.3", only to discover that once I have my schema and validate:xsd-info($doc, $xsd), it can't be processed because the main .xsd uses references that also require the catalog: <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:ditaarch=" http://dita.oasis-open.org/architecture/2005/" elementFormDefault= "qualified" attributeFormDefault="unqualified">  <xs:include schemaLocation=" urn:oasis:names:tc:dita:xsd:abbreviateDomain.xsd:1.3"/> <xs:include schemaLocation= "urn:oasis:names:tc:dita:xsd:deliveryTargetAttDomain.xsd:1.3"/> <xs:include schemaLocation= "urn:oasis:names:tc:dita:xsd:equationDomain.xsd:1.3"/> <xs:include schemaLocation= "urn:oasis:names:tc:dita:xsd:hazardDomain.xsd:1.3"/> <xs:include schemaLocation= "urn:oasis:names:tc:dita:psd:highlightDomain.xsd:1.3"/> My question is: Is it worth it for me to keep going with my ugly parse/replace + export game or is BaseX going to support validate:xsd-info($doc, $catalog) soon? If so how soon? Also, any chance we can keep the DOCTYPE and allow the same type of validation with DTDs? Ya, I know, I'm pushing my luck... but I have to ask because some clients cannot move to schemas. -- France Baril Architecte documentaire / Documentation architect france.baril(a)architextus.com

client:connect reference to DB or storage in RAM (loss in performance?)
by Kapoor, Sumit 20 Jun '16

20 Jun '16

Hello, the Question is: If I open a connection, send a query and close the connection: What do I get? Just a Copy of the Database which will be stored in the core/main memory or a reference to the DB? Here a Code Example: let $cid := client:connect("localhost",port,"user","password") let $query := 'collection("BIG-DB")/*:node' let $req := client:query($cid,$query) let $close := client:close($cid) return $req If it's just a copy in the main memory than (depends on the size oft he DB) it will cost a lot of performance. We have to use such a workaround with "client:connect" because if we try to access directly the DB more than once it will be blocked. So do you have any experience with the return value of "$req" ? Is it still a reference of the DB or is it stored in the main memory?

Re: [basex-talk] Detect if the database is open
by Christian Grün 19 Jun '16

19 Jun '16

I had a look at the actual BaseX sources, and I saw that OPEN is extremely fast if your database is already opened (it boils down to a simple name equality test). Obviously you should only use it if the addressed database already exists. If you want to have a single operation for opening and updating documents, XQuery (with db:add and db:replace) is probably the best solution. Am 20.06.2016 1:03 vorm. schrieb "Kendall Shaw" <kendall.shaw(a)workday.com>: Right now I am just adding or removing documents and executing queries. So, I imagine the time it takes to run CHECK is insignificant. But, if I am going to reuse code, then using the technique of always running CHECK before every operation seem like it might not be the best thing to do. Similarly assuming that my code elsewhere is correctly opening the database and setting a variable to say “isOpen” before it is needed also doesn’t seem like the best idea. But, I gather using CHECK all the time is the typical way to do this. So, I will do that. I thought of CHECK as create or open, it didn’t occur to me that it would optionally open.

Detect if the database is open
by Kendall Shaw 19 Jun '16

19 Jun '16

Using ClientSession from java, I do this to check if the database is open: try { replace(somewhere, new ArrayInput(bytes)); } catch (IOException e) { String msg = e.getMessage(); if (msg == null || !msg.contains(“No database opened”)) throw e; execute(new Check(databaseName)); replace(somewhere, new ArrayInput(bytes)); } Is there a better way to detect if the database is open than testing the exception message text?

CACHERESTXQ always false with basexhttp
by Mathieu 19 Jun '16

19 Jun '16

Hi, I'm trying to activate CACHERESTXQ option while launching from "basexhttp". If I start only "basexserver", CACHERESTXQ value is successfully read it from my .basex configuration file and applied. From the client, "get CACHERESTXQ" return true. If launched from "basexhttp" (see logs below), it read the good value while launching basexhttp. It then start itself the server part. And what's strange, is that the debug show again CACHERESTXQ variable but this time setted to false. Am I doing something wrong? Should this option be set in another way? jetty.xml? Thanks for your help.
