Why is the JSON Schema $anchor not supported?
by Roger L Costello 22 Jun '23

22 Jun '23

When I add "$anchor" to my JSON Schema, the Oxygen editor gives this error message: The keyword "$anchor" is not part of JSON Schema Draft 2020-12 specification. Therefore, it is ignored by the validation engine. But that's not true. See section 8.2.2 of the 2020-12 specification (https://json-schema.org/draft/2020-12/json-schema-core.html#section-8.2.2) Using JSON Pointer fragments requires knowledge of the structure of the schema. When writing schema documents with the intention to provide re-usable schemas, it may be preferable to use a plain name fragment that is not tied to any particular structural location. This allows a subschema to be relocated without requiring JSON Pointer references to be updated. The "$anchor" and "$dynamicAnchor" keywords are used to specify such fragments. They are identifier keywords that can only be used to create plain name fragments, rather than absolute URIs as seen with "$id"...

[ANN] Webinar: AI as a Tool for Technical Content Creation (June 28, 2023)
by Alin Belu 15 Jun '23

15 Jun '23

Hello, On the *28th of June*, we invite you to join us for one of the most anticipated Oxygen XML live events - the *AI as a Tool for Technical Content Creation* webinar! In recent months, AI technology has advanced to the point where it is now applicable in a wide range of real-world situations. However, the AI-generated content is not always accurate, making it challenging to introduce this technology to end users. On the other hand, this is precisely why technical writers are an excellent fit for AI since they can serve as mediators between the AI and the end users, using it to boost their productivity while ensuring the content that they deliver is accurate. *Oxygen AI Positron Assistant* is a new plugin for the Oxygen XML tools that connects to the Open AI Chat GPT engine, introducing AI technology for supporting technical writing operations. To keep authors in control, the workflows are optimized to include preview of proposed AI changes and the possibility to refine the results. Custom AI interactions are also possible, and you can easily reuse them with support to save them as favorites. During this 1-hour live webinar, Sorin Carbunaru (senior software developer at Syncro Soft) will: * Show various use cases for the *Oxygen AI Positron Assistant*. * Explore the available actions and show how they can be invoked, refined, and the results previewed in the visual diff to analyze the document changes. * Demonstrate how you can define your own AI processing actions and mark them as favorites. * Highlight the tasks best suited for AI technology use. This is a free event, but registration is required. You can register at https://oxygenxml.com/evs2023-7.html To stay in touch with us and discover what other events we have planned for you, please make sure to check https://www.oxygenxml.com/events_programme.html Best regards, Alin -- Alin Belu Oxygen XML Editor

[ANN] New release of Oxygen AI Positron Assistant brings chat, preview, new actions, and more
by Alin Belu 29 May '23

29 May '23

Hello everyone, We are excited to announce a new release for the *Oxygen AI Positron Assistant* add-on! Version 0.9.2 comes with a variety of exciting new features, including chat functionality, the ability to preview changes, AI-based quick fixes, AI-based XPath extension functions, and new AI actions for grammar corrections, content rewriting, and checking how your content responds to specific questions. The *AI Positron Chat* side-view provides a better user experience and more control when invoking AI actions, allowing you to see the response and preview its impact on the document using an action that triggers the visual XML-aware comparison. You can also further refine the responses by continuing the discussion with the *AI Positron* platform in the chat view. In a chat message, you can use editor variables that expand to the selected content or the entire document. These allow you to define flexible prompts, and the support to save favorites enables you to store and easily reuse the prompts you find useful. Along with the preview action for the AI responses, you can also use actions to insert the response into your document or copy the response to the system clipboard. Version 0.9.2 of the add-on improves the existing actions and contributes new AI actions: * *Correct Grammar* - Corrects the grammar and spelling of the selected content. * *Use Active Voice* - Converts the selected content from passive voice to active voice. * *Generate Questions* - Displays possible questions that the selected content or the entire document responds to. * *Answer Questions* - Displays AI responses to your questions found in either the selected content or the entire document. The add-on now also helps you with validation problems. If an error message provides a good description of the identified problem and eventually a hint on how to fix it, which is typically the case with Schematron errors, then you can take advantage of the *AI Positron Fix* quick-fix action that tries to find a solution to the validation problem. This action can be triggered from the contextual menu for the validation problems that are displayed in the application's Problems list. The add-on now also contributes two *XPath extension functions* that can be used from XSLT stylesheets, XQuery scripts, and from Schematron schemas to process content or to perform validation checks on existing content. Custom XML refactoring operations (based on XSLT or XQuery) can also take advantage of these AI functions, so you can apply batch processing on multiple documents. For additional information on the *Oxygen AI Positron Assistant* add-on, including the installation instructions, you can check out this article on the Oxygen XML Blog: https://blog.oxygenxml.com/topics/ai_positron.html We want to remind you that we plan to frequently release new features and improvements, so please let us know what you think of the current version and stay tuned for exciting new versions of this add-on! Best regards, Alin -- Alin Belu Oxygen XML Editor

Schematron doesn't respect the full path in the test attribute.
by Danny MacMillan 18 May '23

18 May '23

Hello, Consider the following XML: <?xml version="1.0"?> <root> <relevant> <element relevant-attribute="this attribute exists only on elements under relevant"/> </relevant> <irrelevant> <element/> </irrelevant> </root> And the following Schematron: <?xml version="1.0" encoding="UTF-8"?> <schema xmlns="http://purl.oclc.org/dsdl/schematron" queryBinding="xslt3" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:map="http://www.w3.org/2005/xpath-functions/map"> <ns prefix="map" uri="http://www.w3.org/2005/xpath-functions/map"/> <let name="some-map" value="map {}"/> <pattern> <rule context="/*/relevant/element[map:contains($some-map, @relevant-attribute)]"> <assert test="true()">Impossible</assert> </rule> </pattern> </schema> When I validate the XML with the Schematron, Oxygen prints a warning that an empty sequence is not allowed as the second argument to map:contains, which I've determined is because it is testing the "element" elements under "irrelevant". I know this because if I add a second such element, the error prints twice. If I have 9, the error prints 9 times. But why is it testing that element? I deliberately used xpath that navigates via the parent because I want to include only elements under that parent, but it seems that it's looking at all elements, anywhere in the document, named 'element'. Is this expected? I can silence the warning if I explicitly check for the presence of the attribute: <?xml version="1.0" encoding="UTF-8"?> <schema xmlns="http://purl.oclc.org/dsdl/schematron" queryBinding="xslt3" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:map="http://www.w3.org/2005/xpath-functions/map"> <ns prefix="map" uri="http://www.w3.org/2005/xpath-functions/map"/> <let name="some-map" value="map {}"/> <pattern> <rule context="/*/relevant/element[@relevant-attribute and map:contains($some-map, @relevant-attribute)]"> <assert test="true()">Impossible</assert> </rule> </pattern> </schema> But not if I precede the broken rule with a rule that should equivalently prevent the broken rule from firing on those elements: <?xml version="1.0" encoding="UTF-8"?> <schema xmlns="http://purl.oclc.org/dsdl/schematron" queryBinding="xslt3" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:map="http://www.w3.org/2005/xpath-functions/map"> <ns prefix="map" uri="http://www.w3.org/2005/xpath-functions/map"/> <let name="some-map" value="map {}"/> <pattern> <rule context="/*/relevant/element[not(@relevant-attribute)]"> <assert test="true()">Impossible</assert> </rule> <rule context="/*/relevant/element[map:contains($some-map, @relevant-attribute)]"> <assert test="true()">Impossible</assert> </rule> </pattern> </schema> Thanks, -- Danny MacMillan Sent with [Proton Mail](https://proton.me/) secure email.

Schematron validation of documents using XInclude succeeds when it should fail.
by Danny MacMillan 12 May '23

12 May '23

Hello, I'm going through the Schematron book by Erik Siegel and one of his examples improperly passes validation in Oxygen XML while it correctly fails validation using SchXslt. The code for the book is here: [https://github.com/xatapult/schematron-book-code](https://github.com/xatapu… I open both examples/additional-features/subdocuments-1.sch and data/subdocuments-master.xml from that project in Oxygen and select the tab with the XML file. Then I click the dropdown on the Validation button on the toolbar and click Validate with... and then I select the subdocuments-1.sch file using the dropdown. When I proceed Oxygen says it passes. This is the same approach I have used for all other examples in the book. But I created an explicit validation scenario for this also and it behaves the same way. Note that if you want to test this you should clone the repository because the subdocuments-master.xml file incorporates other files in the repository by reference using XInclude and this is indeed what seems not to be working in Oxygen. By contrast if I run the same validation using the schxslt-cli.jar I get the following, expected result. [invalid] /home/user/task/schematron-book-code/data/subdocuments-master.xml [invalid] /home/user/task/schematron-book-code/data/subdocuments-master.xml failed-assert /Q{}document[1]/Q{}p[1] The class brightred is forbidden (file:/home/user/task/schematron-book-code/data/subdocuments-2.xml)! I am using the latest Oxygen: <oXygen/> XML Editor 25.1, build 2023042509 Thanks, -- Danny MacMillan Sent with [Proton Mail](https://proton.me/) secure email.

[ANN] Boost your productivity with the new Oxygen AI Positron Assistant plugin!
by Alin Belu 03 May '23

03 May '23

Hello everyone, In the recent months, AI technology reached a point where it became useful in many real life scenarios. However, the AI generated content is not 100% accurate, which makes this technology difficult to deploy directly to end users that expect to only receive correct information. On the other hand, users who understand that AI-generated content is only a starting point, a hint, or a suggestion, and that they are in control of the final form, will experience an increase in productivity because the AI generated content will speed up many of their tasks. The new *Oxygen AI Positron Assistant* plugin provides the bridge between AI and Oxygen users, helping them access AI-enabled tools to speed up content creation. The plugin contributes helper actions that can be used to *generate content*: * You can start typing a phrase and use the *Continue writing* action to get a suggestion for continuing the phrase. * You can write instructions for content that you want to be generated and use the powerful and flexible *Follow instructions* action to add the generated content in the document. A group of *translation actions* will try to preserve the XML markup structure while translating the content to *French*, *German*, *Japanese*, or *English*. To obtain *overview* information, you can use an action to *summarize* the selected content or to get *readability* suggestions. *DITA Topic Tools* actions allow you to perform DITA-aware tasks, such as: * Automatically create the *short description* for a topic, summarizing its content. * Generate *index terms* in the prolog section of a topic by analyzing the topic content and extracting relevant terms. * Turn a phrase that enumerates some options into a list with the *Itemize* action. * Flatten a list into content that enumerates the options from the list with the *Join Items* action. * *Generate a new DITA topic* from a title or a short description by expanding the content. * Replace content with a version that*improves its readability*. The Oxygen AI Positron Assistant plugin contributes its actions to the main menu, contextual menu, and in the *AI Positron Assistant* view. When invoking an action, you can monitor its progress and see the results in the *AI Positron Activity* view. To enable the AI features, you need to connect the plugin to the *Oxygen AI Positron* service platform that now uses the Open AI API to access models like Chat GPT, GPT-4, etc. The initial release of the Oxygen AI Positron Assistant plugin is currently in an experimental phase, enabling users to perform up to 250 actions per month, but we expect to provide subscription options in the near future. We anticipate releasing new features and updates often, so please share your feedback about the current version and stay tuned for exciting new versions of this plugin. For additional information on the *Oxygen AI Positron Assistant* plugin, including the installation instructions, you can check out the following article written by Radu Coravu for the Oxygen XML Blog: https://blog.oxygenxml.com/topics/ai_positron.html Best regards, Alin -- Alin Belu Oxygen XML Editor
