Re: [gatein-dev] Dublin Core properties from an image and a HTML code

I used cyberneko to parse the properties inside the html code. My code parses the meta tag inside the html file for example: <meta name="DC.creator" xml:lang="it" content="creator_brand" /> <meta name="DC.date" xml:lang="it" content="2010-01-11" /> <meta name="DC.contributor" xml:lang="it" content="contributor_brand" /> <meta name="DC.language" xml:lang="it" content="it" /> <meta name="DC.subject" xml:lang="it" content="subject_brand" /> <meta name="DC.description" xml:lang="it" content="description_brand" /> <meta name="DC.title" xml:lang="it" content="title_brand /> <meta name="DC.publisher" xml:lang="it" content="publisher_brand" /> <meta name="DC.resourceType" xml:lang="it" content="text/html/brand" /> <meta name="DC.format" xml:lang="it" content="text/html" /> <meta name="DC.identifier" xml:lang="it" content="identifier_brand" /> <meta name="DC.source" xml:lang="it" content="source_brand" /> <meta name="DC.relation" xml:lang="it" content="relation_brand" /> <meta name="DC.coverage" xml:lang="it" content="coverage_brand" /> <meta name="DC.rights" xml:lang="it" content="rights_brand" /> Here a part of the code: .... DOMFragmentParser parser = new DOMFragmentParser(); HTMLDocument document = new HTMLDocumentImpl(); DocumentFragment fragment = document.createDocumentFragment(); parser.parse(new InputSource(is), fragment); setProperties(fragment); ..... public void setProperties(Node node) { if (node instanceof org.apache.html.dom.HTMLMetaElementImpl) { String name = node.getAttributes().getNamedItem("name").getTextContent(); String value = node.getAttributes().getNamedItem("content").getTextContent(); if (name.contains(DCMetaData.CONTRIBUTOR.getName())) props.put(DCMetaData.CONTRIBUTOR, value); if (name.contains(DCMetaData.DESCRIPTION.getName())) props.put(DCMetaData.DESCRIPTION, value); if (name.contains(DCMetaData.DATE.getName())) props.put(DCMetaData.DATE, value); if (name.contains(DCMetaData.CREATOR.getName())) props.put(DCMetaData.CREATOR, value); if (name.contains(DCMetaData.SUBJECT.getName())) props.put(DCMetaData.SUBJECT, value); if (name.contains(DCMetaData.PUBLISHER.getName())) props.put(DCMetaData.PUBLISHER, value); if (name.contains(DCMetaData.TITLE.getName())) props.put(DCMetaData.TITLE, value); if (name.contains(DCMetaData.LANGUAGE.getName())) props.put(DCMetaData.LANGUAGE, value); } Node child = node.getFirstChild(); while (child != null) { setProperties(child); child = child.getNextSibling(); } } I've seen you used HTMLParser in your code. I've no preferences about the parser tools. Simply neko is the first I thought. It is better use a only parser. For the images I used javax.imageio package. You put the properties in the image through some graphic rendering software. The java code extract the properties so: ..... ImageInputStream imgInput = ImageIO.createImageInputStream(is); ImageReader imageReader = ImageIO.getImageReaders(imgInput).next(); imageReader.setInput(imgInput); IIOMetadata metaData = imageReader.getImageMetadata(0); Node fragment = metaData.getAsTree(IIOMetadataFormatImpl.standardMetadataFormatName); setProperties(fragment); ...... public void setProperties(Node node) { if (node instanceof javax.imageio.metadata.IIOMetadataNode) { if (node.getNodeName().equals("TextEntry")) { String name = node.getAttributes().getNamedItem("keyword").getNodeValue(); String value = node.getAttributes().getNamedItem("value").getNodeValue(); if (name.toLowerCase().contains(DCMetaData.CONTRIBUTOR.getName())) props.put(DCMetaData.CONTRIBUTOR, value); if (name.toLowerCase().contains(DCMetaData.DATE.getName())) props.put(DCMetaData.DATE, value); if (name.toLowerCase().contains(DCMetaData.CREATOR.getName())) props.put(DCMetaData.CREATOR, value); if (name.toLowerCase().contains(DCMetaData.LANGUAGE.getName())) props.put(DCMetaData.LANGUAGE, value); } } Node child = node.getFirstChild(); while (child != null) { setProperties(child); child = child.getNextSibling(); } } I published the complete patch in jira On Tue, Mar 30, 2010 at 7:05 PM, Patrice Lamarque < patrice.lamarque(a)gmail.com&gt; wrote: > It looks interesting. > How did you map image/html properties to dublin core ? > > Can you give an example ? > > On Tue, Mar 30, 2010 at 7:00 PM, Luca Stancapiano < > l.stancapiano(a)sourcesense.com&gt; wrote: > >> Hi...
