Wicket and microdata
I'm currently try to add some kind of microdata
(http://en.wikipedia.org/wiki/Microdata_%28HTML%29) to our project. Exists a
wicketstuff project dealing with this problem?
What is the preferred way to add "valueless" attributes to HTML tags? E.g. I
have to add the following attributes to the body tag:
<body id="foo" itemscope itemtype="http://scheme.org/WebPage">
</body>
At the base page class I've added a TransparentMarkupContainer the following
way:
this.body = new TransparentWebMarkupContainer("body");
this.body.setOutputMarkupId(true);
HTML:
<body wicket:id="body">
<wicket:child/>
</body>
At a subclass I did:
getBody().setMarkupId("foo").add( AttributeModifier.append("itemscope",
AttributeModifier.VALUELESS_ATTRIBUTE_ADD ) ).add( AttributeModifier.append(
"itemtype", Model.of( "http://scheme.org/WebPage" ) ) );
Is this the preferred way to add "valueless" attributes to a tag (I've never
seen this before)? Or is this marker value for internal use only? At least
the generated HTML code looks like intended.
I would like to know whether there is a kind of general solution to deal
with "microdata", say a bunch of Behavior-classes to add this kind of data.

Feel free to contribute your code as a module at
https://github.com/wicketstuff/core if you think it would be useful for
others and it is reusable.
Thanks !

Here's what I came up with :
https://github.com/soluvas/soluvas-web/commit/8cfbe121bc8589502154bf72fff9bd94762dd7cb
While my usage is for e-commerce websites, with sufficient definitions it's
usable for any kind of site, primarily using schema.org vocabulary. IMHO
it's quite convenient (thanks to Wicket's Behavior programming model, yay!)
and also type-safe (no Strings, ma!).
Usage examples:
final WebMarkupContainer productDiv = new WebMarkupContainer("productDiv");
productDiv.add(new ItemScopeBehavior(SchemaOrgClass.PRODUCT));
...
protected void populateItem(final ListItem<ProductImage> imageItem) {
imageItem.add(new ImageMicrodataBehavior());
...
final Label descLabel = new Label("descriptionHtml", new
PropertyModel<String>(model, "descriptionHtml"));
descLabel.add(new ItemPropBehavior(SchemaOrgProperty.DESCRIPTION));
...
inStockLabel = new Label("inStockStatus", "In Stock");
inStockLabel.add(new ItemPropEnumBehavior(SchemaOrgProperty.AVAILABILITY,
ItemAvailability.IN_STOCK));
add(inStockLabel);
outOfStockLabel = new Label("outOfStockStatus", "Out of Stock");
outOfStockLabel.add(new ItemPropEnumBehavior(SchemaOrgProperty.AVAILABILITY,
ItemAvailability.OUT_OF_STOCK));
add(outOfStockLabel);
...
currencyPriceAfterDiscountLbl.add(new
ItemPropContentBehavior(SchemaOrgProperty.PRICE_CURRENCY,
new PropertyModel<CurrencyUnit>(selectedProductModel, "currency")));
add(currencyPriceAfterDiscountLbl);
final Label priceAfterDiscountsLabel = new MoneyLabel("price",
priceAfterDiscountsModel);
priceAfterDiscountsLabel.add(new
ItemPropContentBehavior(SchemaOrgProperty.PRICE,
priceAfterDiscountsModel));
...
localSkuCtr.add(new Label("localSkuValue", new PropertyModel<>(productModel,
"localSku"))
.add(new ItemPropBehavior(SchemaOrgProperty.SKU)) );

I agree. Some markups are customizable by designers, I'd rather let them
worry about presentation structure rather than semantic data, which are
closer to the model.

I thought someone has had the same requirements within his project and came
with a general solution for this specification. Okay, fair enough.
Martin, "This [microdata] specification is not broadly used." some of us
disagree with that ("some" refers to Google, Bing, and Yahoo, for a start)
;-) : https://blog.kissmetrics.com/get-started-using-schema/
Dirk, yes I have exactly the same requirements as yours for Bippo
<http://www.bippo.co.id/> . Do you share your solution somewhere?
I'm planning to put my work as part of soluvas-web project on GitHub
<https://github.com/soluvas/soluvas-web> since it's most comfortable
within our build environment, but if anybody wants it in wicketstuff I can
also contribute.
Thanks.

Okay. I've never seen this before. That's why I was asking.

Yes, but I prefer the "dynamic" way. A Component/Page provides some kind of
"microdata" and implements an interface. The AttributeAppender takes the
information and writes the appropriate attribute at the tag.

I thought someone has had the same requirements within his project and came
with a general solution for this specification. Okay, fair enough.

Yes. This is the way to tell Wicket to not add a value for the attribute.
Another way is to add these attributes directly in the markup. No need to
add Behavior to the components for something that is always true.

AttributeModifier is a Behavior itself.
There is no special code in Wicket for microdata. This specification is not
broadly used.
